I'm not sure if you care about trophies or achievements like that, but just in case you do, there is two co-op trophies/achievements that you are better off knocking out from near beginning of the game or asap.

One of them is beating 15 missions total in co-op. (Those missions where all you have to do is just walk from point A to point B and talk to somebody/pick up something count towards this, so thats why its one of the easier ones to do near the start of the game where there is a bunch of "missions" like this). The other is you have to beat 1 of 5 certain bosses while playing co-op with someone. Either the rakk hive, the vault boss (last boss), sledge (the first major boss), krom or flynt.
