A co-op and DON'T CHANGE THE CONTROLS!!!!!!!!!! Call of Duty's controls are way to easy and noob friendly.

Better controls. The controls in the 2nd one are fine, but they feel so damn slippery like soap. Something adaptable like Cod.

Shorter load times.

If you're referring to the pic I posted, yes. On the cruiser level you'll find them.

I would say, they should improve the controls a little, they are great but can be improved and the story could be a little better.
Online should stay about the same with maybe more options and some cool maps.

A deeper story. Dogs sounds cool. MANY MORE GUNS! Local 4 player co-op and 4 multiplayer splitscreen, this is a must.

colors, colors, colors,
colors, colors, colors

when i see Uncharted, or Gear of wars, the choice of Kilzzone to the monochrome is becomming very boring.
More diversity and flashy colors.

Vegetation, and people,

The wolrd of hellghast seems false,the town are not credible, no citizens, no stores, no cars or hover car...

and the sound o guns is poor.

i really hope KZ3 'll be more diversified, why not on earth ?

Yes, hellghan on Earth

stick to calls of duty :)

Sweet, good to know! *runs off to play that level and gawk at the helghast awesomeness*
