@buccomatic door clipping is still there, NPCs are dumber now I guess, they can't even open/close door properly.
screen tearing wasn't a problem for me, and the v-sync is not an option, it's just there.. no performance issue though - but the slowdowns at +20 zombies areas are still there...
anyways, much improved and the game seems easier now - before I could only accumulate around 500 influence per gameplay, now I have over 2.5k influence and nowhere to spend all that!!
thing is, PSN+ games turn to demo as soon as you're not a PSN+ member...
in XBL you can pretty easy get a 2-day gold trial code or something, download and keep the game. you could do that for each free game you see and still keep it.
