Played some multiplayer rounds today, I found it really fun, though it basically boils down to:
Human team: Let's go running, get killed, respawn, run, get killed, respawn, take objective, get killed, respawn, run again, and that's it until you win the round
Necromorph team: Go, damage human, get killed, respawn, kill human, possibly kill another human, get killed, respawn, rinse and repeat until you win.
Even so, it's a fun mode
So yeah, now that I've finished the campaign, I'm up for some PS3 matches if anyone wants to play
