Your strategy should be based on maximizing Time's Vengeance, not least because the sooner you kill Atheon the less glitches you will experience. This means you must jump in the middle platform and put up the shield with 30 seconds to go! To achieve this you must do the last cleanse before your teammates start shooting the last two oracles. After this cleanse, leave them in there to finish the job and get in the middle. If your timing is spot on, you will be putting up the shield as the last oracle is destroyed - your teammates then get cleansed on the middle platform. During the last cleanse your teammates must be together, cleanse them at the bottom of the steps, they should always be together as they are shooting, keep an eye on them and let them know if a gap appears between them. You should cleanse them three times, at the top of the stairs, in the middle somewhere and at the bottom of the portal steps. You can use your super to shoot down the 4th, 5th or 6th oracle. The less cleanse time you use the faster your super will charge so again it helps if your teammates are together. Let everyone know when you are exiting the portal so they can get ready to jump in the middle. If you meet a supplicant on the way out, use light attack to kill it. When you jump on the middle platform, make sure your shield isn't touching the pillar on the left. If it does, you can get splash damage and you could all die so stand on the right at the front. If you look down you will see a horseshoe shaped crack on the floor - stand in it. Weapons of light should go at the back, sometimes this can cause splash damage as well. I'm not sure if it's because it too overlaps the pillar or because it overlaps the shield thereby acting as another pillar. Avoid both by putting it at the back right of the middle platform. Don't move about when the shield is up and your teammates must not bump into you. Everyone should stand still. Jumping out of the shield and firing rockets is silly, if your going to fire rockets don't jump into the shield, or fire them as you jump out. If there are supplicants tell someone to break off and clear them. You don't need to look around, you can tell by the amount of red sections on the radar. Call out when 10 seconds of Time's Vengeance is left. At five seconds tell everyone to get out. Don't leave until they are leaving. Also don't leave if Atheon has just launched a barrage of rockets at you. Make sure you are on the ground as soon as possible, preferrably in a sync plate so that if you get detained you can activate the portal while shooting your way out of the bubble. If you have time you can super supplicants as you are jumping out, or super Atheon if there are no supplicants and you have a clear shot. Killing supplicants is high priority so they can't go inside detain bubbles and kill teammates. As for clearing the portal of enemies you should obviously use the relic smash. This is simple if the enemies are together and they don't see you coming but some spawns are more difficult. Mars is easiest but sometimes they are all facing you and see you coming. If they charge up to shoot while you are in the air, you can use light attack to dodge their shots. This helps a bit but it helps more if your teammates are aware of this spawn and can shoot the enemies forcing them into their defensive stance. Better still precision shots will one shot them. It's not necessary to shoot them under any other circumstances unless one of them is separated from the other two, in this case you can smash the two but there is a chance you will get sniped by the third so having a teammate shoot him to put into that defensive stance will give you more time to close the gap and kill him after your smash. If you do get sniped then you must ensure your next attack kills him - you won't survive two shots. If you find yourself with two mobs on either side and you need to close a big gap to both of them, you can use light attack to dodge their shots and close the gap quicker. Don't run straight toward them as they are about to fire, move left and right and if you are lucky they sometimes miss. Sometimes your smash will push them a fair distance from your position so use these tactics to close the gap. On Venus it helps alot if your teammates can shoot off the minotaurs shield. If the shield stays on then you will find yourself in a time consuming battle with the minotaur while being sniped from the other enemies. For this reason you should smash the other enemies *before* the minotaur. Doing this gives you plenty of time to battle the minotaur without being sniped but make sure your smash does him some damage or he might decide to teleport up the steps and attack your teammates. When fighting the minotaur attack him from the side and his frontal attack will pose no threat. So after an attack move to the side and do it again. You should also jump and use the relic smash as much as possible. If you lose track of where he is, use the radar to locate him. You don't need to go down the steps to attack them, you can go down the side. I've not done this, it seems a better way to avoid being sniped before you attack but I think there is more risk of your teammates being attacked.
