Does anybody know the name of that game published by ACTIVISION in 2000s or early 2010s. This was a shooter game in which there were 4 or 5 different characters and one could play with each of these characters. The game environment was a post apocalyptic world that was run by corporate and we were part of an uprising group. In this game when we get killed we could respawn in some devices inside the game that used a bright fluid.
