Call of duty 4 plus WAY more.
Now the shine of this game is mostly in the multiplayer aspect. The weapons, perks and maps are all amazing. Nothing seems too over powered because there are weapons and perks that combat each other which balances out the game. The killstreaks are cool and the challenges, although similar to call of duty 4, still seem fresh and fun to achieve.
The only negative thing i could say about this game is the campaign is way to easy, especially on veteran. i was expecting it to be more of a challenge, but nonetheless is was still enjoyable.
i would greatly recommend this game to anyone who is a fan of fps. oh and btw they do have a thrid person online mode which is quite fun and appeals to different players.
look forward to seeing you on the battlefield.
