I had dreams about an Alien mmo game.
Big multiplayer PvE game about storming stuff in 20+ player teams, with important stuff that a group sometimes needs to split to raid two different locations at the same time. One goes to reactor, second goes to raid the top of the facility. And escape extraction sequences. Almost like 16-20 player L4D.
The teams very rarely consist of Marines, but also sometimes can have a Predator that temporarily cooperates with humans. Or an android. With a caveat that you actually need civilians to do things, like hacking a computer or piloting an escape dropship.
Remembering the distinct part of while the rest of the big squad was trying to breach a huge locked door, me and two more "dream" players were guarding the side ladder -- the game does not obviously telegraph the incoming enemies like L4D, so you'd need to have real eyes on something and SCREAM if something happens -- you may not even have a working motion detector.
And the rest of dream is now slipping from my mind.
