PS3 VS PC + other random thoughts:
Huge difference
For one, the central building on PS3 never once collapses
Time feels off on Parachute jumps on PS3 as well
Lag was easier to manage, but was tricky at times. (This isn't really a concern of mine though as its a beta)
They changed the controls up completely, annoying, I actually prefer the Mouse and Keyboard this time around.
The Commarose (The Gimme health/ammo button) is pointless (both systems)
Dude! Where's my ammo! (Seriously, where is my ammo you fuckers, why am I equipped with a PDW and only like 80 units of fire? I waste that on walls and sidewalks most fights)
Elevators are horrible death traps, and the Chopper crews need to get their shit together to keep the roofs clear and STOP WORRYING ABOUT CAPPING FLAGS!! The rest of us can do that if you just kill those damn snipers! (Also, chopper crews, grats on your roadkill..... Why are you "teabagging" the poor sod now? thats just begging for an RPG round....)
