Totally agree Matt, it works best as a squad based game but i still have a lot of fun when my mates arent on and i can then catch up with using classes and guns that i dont really use when in the squad.
Vibra, you have to get to know the maps and where the sneaky snipers are likely to hang out, you do get a brief replay of where the sniper was located but it can still be tricky to work out just exactly where they were plus they move about. It can be frustrating at first but im sure you would pick it up pretty quickly. What i like to do is go and stab-up the snipers, that gives me lots of pleasure!
Try renting it from Blockbuster for a week to see if it floats yer boat or not.
The only downside at the mo is there arent that many maps in Rush mode (which is my fav mode) but i do understand that there will be Map packs etc on the way.
Give it a whirl!
