Everyone has their particular role when it comes to taking down Atheon. When you are split into teams, you only get to see the strategy of one perspective, you don't see all the tricks and strategies the other side has to employ. Because of this, I will do my best to explain all the positions.
So concluding Area 4, but before starting Area 5, it is extremely important for everyone to know what the strategies are and what their roles are for the upcoming boss fight.
There are not any delays between each of the phases. While you get checkpoints, it's always a good idea to at least aim for a Wipe-free playthrough. Since there are no delays and you cannot pause, everyone needs to know their roles and strategies for each phase ahead of time, not halfway through.
So that all your team members are clear, it is important to clarify what is the left side and what is the right side of this map.
Some people will immediately just know which is which and some may need a little help.
When you enter, you will see 2 Vex Portals as well as a Portal Control Pad for each of the Vex Portals. Standing between these landmarks, the map basically ramps up in the far back and converges into basically an arrow head.
Facing the far end of the map, your Left and Right sides can be established.
So now, Left = Left, Right = Right, Back = Far end of the Map, Rear = Behind you.
Phase 1: Killing the Gatekeeper
There are no tricks to this part, it is pretty straightforward.
• Step 1: Clear out the Dormant Vex / White Vex
• Step 2: Kill the Gatekeeper
Phase 2: Collect the Relics and Defend the Structures
Chaos immediately follows Phase 1.
In order to complete this section, you must seek out the Gatekeeper who has teleported itself into both the past and the future. You must kill the Gatekeeper to collect the relics it drops, return them to the present time, and finally protect the "Keymaster"
in order for the final boss to appear. The "Keymaster" is simply a structure that appears in the middle of the map that must finish being constructed in order to move on to the final phase.
This phase requires you to incorporate some of the strategies from both Area 1 and Area 3. It is a combination of the Control Pad protection of Area 1 and the Point-Defense from Phase 1 of Area 3.
Initially, you will split into 2 groups of 3, but you will have to split into groups of 2 fairly quickly, so making sure everyone knows who their partners are and who will be splitting up is very important.
NOTE: During Phase 2, the enemies spawn from both the Rear side and the Left side of the Left Control Pad and they spawn from both the Rear side and the Right side of the Right Control Pad. There is also a spawn in the Far back of the map that you need to keep in mind, especially after getting your 1st relic.
The Left Control Pad seems to see A LOT more Praetorians than the Right Control Pad does, this is a very crucial aspect to keep in mind when forming your strategy.
Defending the Control Pads:
If the Praetorians get too close to the Portal Control Pad, it will close the Portal, causing the Time Travelers to become "lost in time", which results in a team wipe.
This is similar to the mechanics of the Control Pads in Area 1, if an enemy enters the circle, it gets reset. With the Tower in Area 1, you could rebuild it if it got reset, but with the Portals, if you fail, it results in being wiped.
I strongly recommend the team who will be staying in the present time to protect the Control pad to all have Void Fusion Rifles or at least a Void Sniper Rifle (which you will switch to your primary after lowering a Praetorian's shield with the sniper.)
Save your Heavy ammo and your Super Abilities for the Praetorians. Communicate with one another and call out all the spawns, and if you are about to use your Super or a Rocket Launcher.
Part 1: Clearing the Gatekeeper out of the Past
The Past is the Left Portal. For this, you will split into 2 groups of 3.
You want to start working on this immediately after clearing Phase 1, so having everyone already on the left side is going to be very important.
3 Team members will go into the portal and 3 have to stay outside and defend it.
You can be successful sending only 2 individuals into the portal, but for clearing the Past Timegate, you want to be fast and efficient.
Only having 2 people inside the portal means that you have to deal with the Praetorians on that side for a longer period of time.
Why do the left side first?
It is critical that you do it first, because after you complete one of the portals, the Keymaster appears, and now you have to divide your attention split among dealing with 3 things instead of just 2. What this means, is that when this happens, you don't just want to have 2 players trying to fight off all the Praetorians around the Left Control Pad, you REALLY want to have 3 otherwise it can be seemingly impossible.
Obtaining the Relic:
When you kill the Gatekeeper in a Timegate, it drops a Relic you need to pick up.
Grabbing the relic resets your Super Meter, but it also causes it to be recharged rapidly.
When someone picks up the Relic, it causes a debuff called the "Mark of the Void" to be applied to all those who are within the Timegate. While the Mark of the Void is active, you must cleanse yourself periodically to avoid dieing.
Mark of the Void will stay active once you leave the Timegate back through the portal. You need to cleanse yourself and your partner(s) again in order to clear yourself of the debuff. It will not reactivate itself in the present time after doing so.
* * * REMINDER * * *
Please refer to Area 3: Phase 3 (above) for in-depth details on the Relic Shield Controls
Make sure that when you exit the Vex Timegate Portal that you
walk through, not run, as it seems that running can cause the game to glitch and you can get stuck inside the portal.
After returning from the Portal and cleansing your partners, everyone immediately needs to switch their roles up and their positioning for the next part.
Part 2: Clearing the Gatekeeper out of the Future AND Protecting the Keymaster
The Future is the Right Portal.
Your original 2 teams of 3 must now break up into pairs.
• Pair #1 = The Relic Holder from the first portal and one of his original partners.
• This pair's mission is to retrieve the 2nd Relic
• Pair #2 = 2 of the Control Pad protectors from the first portal
• This pair's mission is to keep the Right Control Pad open for Pair #1
• Pair #3 = 1 of the Relic Holder's original partners and 1 of the original Control Pad Protectors will split and form a new team.
• This pair's mission is to protect the Keymaster from the enemies that spawn from the far back of the map.
Upon entering the 2nd Portal, have the Relic Holder perform a Super on the boss.
To perform a super with the relic, hit LB + RB. This will shoot a projectile similar to a Warlock's Nova Bomb just like it did against the 1st boss.
The Relic Holder's Partner will need to use Heavy weapons, grenades, etc in order to finish off the rest of the enemies and continue to damage the boss. An LMG could be used, but a Rocket Launcher is recommended so that you can damage all the remaining enemies and the Gatekeeper at once.
Make sure to have the Relic Carrier cleanse himself and his partner as they continue their assault on the Gatekeeper.
Once the Gatekeeper has fallen, the partner of the original Relic Carrier will grab the 2nd Relic.
Carefully make your way through the portal and have everyone regroup at the Keymaster (the structure forming at the center of the map) to defend it.
At this point, all you have to do is continue to kill the enemies until the Keymaster finishes constructing itself and the Phase ends.
NOTE: Keep in mind, that if the Relic Carriers are killed and the Relics are dropped at any time, it will result in a wipe.
Phase 3: Killing Atheon
In order to kill Atheon, very good communication with your team members needs to be established. You really need to know what your strategy is coming into this. Everyone needs to know their role, and everyone needs to know everyone else's role in case they find themselves playing it. If you are going for a deathless run, you need flawless execution, just like you do with every other section, but this section is even less forgiving than all the rest (with possibly the exception of the vanishing platforms).
You will be split into 2 groups of 3, the game will do this forceably, so if people are out of their positions, it can cause a lot of unnecessary chaos.
Your 2 groups are:
• The Vex Timegate Travelers, and
• The Portal Protectors
The 3 players who are the furthest away from the boss will get teleported. If you are not on the Vex Timegate team, get away from the ones that are. Go forward towards the boss over by the portals.
Splitting up the Team:
For the best results, I recommend that the Timegate team have 2 Gunslingers and have 1 of the Titans be the Relic Holder with their passives set for maximum armor and/or recovery.
On the outside, you'll have the Portal Protectors be 2 Sunsingers and a Defender Titan.
While any mix of classes can work for the Timegate's team, it is best to make sure that the two players who are with the Relic Holder have ranged Super Abilities, so the Voidwalker and Gunslinger are great here. A Striker would also work well, but they will always be in the rear if they are in the group, rather than switching off with whoever is in the front.
Portal Protectors:
You will divide up, 1 left, 1 right, and 1 support in order to open up the Return Portal Pads for the Vex Timegate team. Besides opening the Portals, you need to kill off all of the exploding Harpies that spawn from the back of the map behind Atheon. These
will 1-shot you if they explode too close to you.
As I mentioned above, it would be a good idea to have Sunsingers for this portion. Have them play as the fixed Portal Protectors, with the Titan playing the Support Role. The only time I would mix this up is if the Titan has better equipment for dealing with the Harpies.
Sunsingers are the best choice for this part because if they die, they can come back.
When the Timegate team gets teleported, they need to inform the Portal Protector team whether they have entered the past or future (left or right). When this happens, the Support player will jump to the side in which the portal needs to be opened if they are not already there.
The guardian that is defending their side solo does not need to worry about opening a portal, they need to only focus on cleaning up Harpies on their side and surviving.
For the 2 guardians on the side that the portal needs to be opened, it is better to keep the Titan up the ramp by the portal and the Sunsinger down below by the Portal Control Pad. When the Time's Vengeance buff activates, the Titan should deploy his bubble shield near the portal, so that the Timegate team can make a safer return without as much fear of worrying about a Harpy exploding in their face as they walk through the portal.
The Vex Timegate:
Desert = Brown = Past = Left Portal needs to be opened
Forest = Green = Future = Right Portal needs to be opened
There are 7 Oracles
If you don't kill them all, you get Marked by the Void.
If you DO kill them all, you get Time's Vengeance.
Time's Vengeance = 30 second Damage Boost + Max Super about every 3 seconds; awarded for killing all 7 Oracles.
At the end of each Time's Vengeance, Atheon will reset the Portal Pads and destroy the Relic, so you have to grab it again the next time you go in.
Marked by the Void = If you don't kill an Oracle, especially before going back through the Portal, everyone will die.
Not sure exactly how long you have before you get auto-killed
When you get teleported/time travel, it can be disorientating and sometimes the game likes to spawn you facing the wrong way every time.
• When you spawn on the Forrest side, look for the tree.
• When you spawn on the Desert side, look for the cubic stone structures (not the tall angled ones you spawn under)
Timegate Walkthrough:
There is more than one strategy for dealing with the Timegates, there is the Defensive strategy and the pure Offensive strategy.
• In the Desert, you will face 1 Goblin and 2 Hobgoblins.
• In the Forrest, you will face 2 Goblins and a Praetorian.
That 1 Praetorian can be the hardest part of this entire phase. Make sure to keep a Void Fusion Rifle and Rockets on hand, you might need them.
When the enemies are taken out (which should be done very quickly), the person in the front needs to help the person who stays in back take out the Oracles while the Relic Holder continues to Cleanse everyone periodically.
Defensive Strategy:
For both Timegates, you will want to be in a line that has someone with a ranged super up front (Gunslinger), the Relic Holder in the middle, and your 3rd person behind him.
The person up front is in charge of taking out the enemies down below as the player walks to the front of the staircase you have to descend, while the player in the back is in charge of clearing the 1st Oracle that appears over the top of everyone and picking any up while the Front-Man finishes off the enemies. If the enemies make it up the stairs, the Shield can be used to melee the enemies, and if there is a Titan in the back, they can use their Fist of Havoc to finish the enemies off (hopefully).
Offensive Strategy:
I have seen the Praetorian survive 3 Rockets, a Fist of Havoc and 2 Ground Pounds from the Relic Holder. Only after a 3rd Ground Pound did it die.
* * * REMINDER * * *
Please refer to Area 3: Phase 3 (above) for in-depth details on the Relic Shield Controls
I think that the best Offensive Strategy combo makes use of a Hunter Gunslinger and a Titan Striker in addition to the Relic Holder.
When you are about to get teleported, switch to your Rocket Launchers, inside the Timegate, immediately rush over to the stairs, jump up and rain down one of your Rockets onto the enemies below.
Make sure to switch back to your primary after firing your Rockets (and bring Rocket Launchers that can hold 2+ Rockets)
The Gunslinger will stay near the top of the stairs while the Titan will continue their jump over to the enemies, ending in a Fist of Havoc. After using it, the Titan will immediately turn towards the Gunslinger, killing the 1st Oracle above them and retreat back up the stairs, then they need to turn around to focus on the remaining Oracles with the Gunslinger.
The Gunslinger has the option to use their Super on the enemies below or to use it on the Oracles.
While all the above is going on, the Relic Holder should be following shortly behind the Titan, jumping in with a Ground Pound and protecting the Titan's retreat back to the stairs. Repeatedly using Ground Pound seems to be superior to using the Shield Bash against the Praetorian.
After the Praetorian and all the enemies are down, the Relic Holder needs to immediately get back to the staircase and cleanse everyone before they work on making their way forward down the rest of the staircase and through the area as they kill the remaining Oracles.
Once you have cleared out the Vex Timegate area and approach the portal, make sure that you
Walk through. If you don't walk, you can glitch it so that you are stuck inside the portal.... which then kills you.
Make sure that the Relic Holder Cleanses you after you exit the Portal, otherwise the black-screen effects continue until you die.
Damaging Atheon
This is where most Guardians fail to succeed even though they have everything else down.
With Time's Vengeance active, everyone needs to jump onto the square platform in the center. The Relic Holder will keep the Cleansing Shield up to negate incoming damage while 4 of the 5 other players focus on damaging Atheon and the 5th man focuses on taking out the evil exploding Harpies so that the Portal Protectors can safely return to their posts.
When there is about 5 seconds left over, have a Defender Titan spawn a shield while the Vex Timegate team jumps to the rear area to be teleported again and so that the Portal Protectors are also fairly covered returning to their positions.
NOTE: When Time's Vengeance counts down to 0:00, you have
maybe 1 second before 3 people get sent back into the Timegate. Make sure everyone is where they need to be for this. The Portal Protectors should jump towards the Portals (rather than the Control Pad) when they depart from the central square platform to try and avoid causing any confusion for the game in terms of who it will send into the Timegate.
Remember that at the end of each Time's Vengeance, Atheon will reset the Portal Pads and destroy the Relic, so the Portal that needs to be opened will need to be opened/reopened and the Relic will need to be picked up once again.
If your Portal Protectors are extremely efficient at killing the Harpies on their own, you can be extra efficient at damaging Atheon by having all 5 players focusing on damaging him instead of just the 4 with the 5th killing Harpies.
If all your team members are good about checking the remaining time (or you can just have the Relic Holder call out the remaining time, or just say "MOVE NOW"), you can be extra efficient at damaging Atheon by getting a few extra seconds of damage in. You want the Portal Protectors to go ahead and jump out first when there is 2 or 3 seconds remaining on the timer, and have the Timegate Travelers turn around and jump back when there is 1 second remaining. The Relic Holder should already be facing the rear side, ready to jump, but they should always check the front side when they get on the platform to make sure everyone is covered. The Timegate Travelers should attempt to reload their Rockets (if they have emptied all their rounds in previous Timegates) while they jump back to the rear section.
If you find yourself blowing through your Rockets, or even your primary ammo, the best time to use an Ammo Synthesis is likely while Time's Vengeance is active and you are protected under the shield, but keep in mind that while you do this, you are sacrificing a lot of precious boss smashing time.
Critical Hits on Atheon:
There are several rumors going around currently on how to score critical/precision hits on Atheon. Some people have been saying that you need to shoot the Cables that lead to Atheon's stomach core to score a precision hit while some have even said that he can just turn it on and off.
I haven't noticed a particular pattern to get successful precision hits while using a sniper rifle, so it's hard to judge what is best.
I will say though that the Portal Protectors might like to switch to LMGs during the battle (or between wipes) because Atheon does move around a lot which can cause you to miss with a Rocket.
There are 8 minutes until Atheon enrages.
Enrage is Near = 1 Minute until massive spawn of enemies
You should be able to kill him before that happens. If you can't, either you have members dieing, you have players that aren't high enough in level, or you are using weapons that are not as upgraded as they need to be.
