uM aCtullAY. Friendly can be used to refer universally in any game, they won't attempt harming you and would often just follow you, watch from a distance, etc. Sometimes they also help. Though they can be interchanged with No Kill, it's just that No Kill is more associated with some type of servers.

Uber is actually used everywhere in the game (assuming zombies also exist there) and is not limited to be typically found in no kill servers but I guess it's okay.
