-Cell's Visor should be transparent, be able to see there eyes, like in MP.(I really want this)
-Wooden Crates should be collapsible., and grab-able,
-Allow the ridiculous option of putting a sniper scope on a shotgun,(its the though that counts)
-Fix the AI's reaction to sniper Fire, at least make a cool WTF? animation from the cell dude.
-Allow dead bodies to be tossed, hey, its improving upon the first remember?
-Interact with civilians., like punching them.
-More stealth kill animations.
-Reactions to crotch shots.
-More appearances of Elite Nano Aliens, ya the ones with your suit powers.
-Air stomp is useless in campaign.
-Spiff up textures, and i mean really, spiff up.
-Make AI more aggressive, not there bullets stronger.
-What ever happened to Shooting buildings, and chunks would fall.
-WTF, what happened to physics? Rocks and debris just disappear.
-Make the Feline usable towards the end.
-How about cars react more than if there just bricks with wheels?
-Obviously "pop" from Dx11.
-More torn up flags to give it an apocalyptic feel.
-how about more diversity in cars, I'm tired of seeing a wannabe Bently's as New Yorks common car.
-How about some rock throwing?
-The Sandbox hasn't been released yet so these things could be easily installed. Maybe thats the reason o_0
-Not consume energy while holding a cell by his throat, make him a shield from bullets.
-Making cab doors into riot shields, city warfare remember?
-Parking meter baseball bats.
-How about Nanosuit 1 marines, you obviously dew them up already for the game, just insert into a marine.
Make this game last, and not just something people put aside, when the next FPS comes out.
Crytek, as a reminder, you could hold the price of Crysis 2 at a $60 range much longer, and probably more PC gamers would instantly buy the game with these improvements.
This is all I got people, But please keep adding! Crytek should react,......seeing how all there PC servers are full, :S, shows how many people actually were pissed with the PC version.
