Sorry if this has been posted before (I did look but saw nothing). I'd like some friends for high-score comparison and possibly co-op for anything by Housemarque!
If you're interested, how about putting your PS4 username and what Housemarque titles you play in this thread...
PS4 username: the_greeze
I play: Nex Machina, Resogun, Super Stardust HD, Dead Nation
Hopefully we can get a little competition and co-op going?
