I was going through the story again with my friend and found out how to cheese Riksis incase anyone is having trouble beating him (the archon on the first mission on earth that comes out of the hole in the wall). You need at least 2 people, have your friend go do the first objectives while you go to Dock 13 and clear out the enemies in advance. Leave at least one enemy alive so Riksis doesn't spawn yet. Once your friend is done with the map room, have him start heading to you, but DON'T LET HIM enter darkness zone yet. Once your friend is close enough, kill yourself along with the last enemy with an explosive or something and have your friend run in to the darkness zone while the countdown is going. If you time it right, and your friend makes it into darkness while the timer is going down, your ghost will say "it's in the walls!" and Riksis will spawn inside the hole in the wall, but not come out. Your friend can revive you or just shoot at Riksis and he won't do anything. I hope this helps anyone still stuck on the very first mission. EDIT: LMAO at the people who think this is serious or that I actually need to cheese Riksis. This post was targeted at people who cheese the raid bosses, I found this one by accident and am not even sure if this "Riksis cheese" is replicable or not.
