Nothing really. it's pretty good as it is.

simply add a cover system...

just like the new James Bond game will get .....

Definitely a longer campaign.

More ppl online, i like the BF2 feel. But then again, its perfect how it is

i hope they addess every issue in this and make cod5 the greatest online game ever made. world at war should be an improvement as well, even though its ww2 it will still be better in some ways

A longer singe-player campaign and online co-op.

health bars.

no fucking martyrdom or claymores. basically anything that gives you an indirect kill should be removed

"Longer single player"

"Co-Op single player"

I'd make it so I was invincible.

More dynamic and natural multiplayer, I hate it how everyone ALWAYS spawns in the same place all the time. Its like, oh I spawned here, so the enemy has to have spawned over there. It ruins it for me. Also maybe destructible environments.

i would put in co-op, sort out grenade spawns and add a few more maps.

no... more... 3 frags...

also juggernaut and martyrdom should be gone since they just cancel each other out and most people just go with one or the other, and then the other red perks are ignored. but u guess its all about what kind of strategy your going with.

"Infinite spawning points in single player"

Make the multiplayer have some achievements. Campaign longer. Co-Op Campaign. A good reason to go prestige rather than just a symbol. Maybe getting more than one gun attachment. (I would love red dot sight and a silencer....)
