Multiplayer vs. Campaign
The bad thing about campaign is that you ' ll find out that your the only 1 fighting this war . your team mates basically "pretends" to shoot at the enemy and ...die . But you also get a good warm up for when u play multiplayer .
In my opinion they should make a 1st person shooting game that u can actually play campaign mode online . that would be a better game and more challenging . Well like i said its only my opinion .
