http://uk.pc.ign.com.../1172554p1.html TL DR. 4 classes. Riflemen: Combo of medic + assault, heals and revives. can probably chose unlocks between nade launchers or medic stuff like defibs.Support class: LMG and can suppress, also gives out ammo. ( Probably has a shotgun unlock looking at 2142 and other cool stuff )Recon ( or sniper ), Probably the sniper kit.Engineer kit: repairs and destroys vehicles. nuff said. LMGs have suppression. Vehicles repair HP SLOWLY, to low to be reliable but probably good enough to GTFO with. Scopes have lens flares, easier to spot snipers.
