I didn't feel challenged on the campaign and I played it on the hardest setting. The AI doesn't handle sniping well.
The campaign is very short, I cruised through it in an afternoon. The campaign story-line is good and the campaign gives you a healthy boost of credits for multiplayer purchases, but it isn't enough to sell the game of its own right.
I can not recommend the game if you can't play the PvP content online.
