WarRock Brazil

You are at war! Choose your role in this war among 5 classes: Assault, Sniper, Engineer, Medic, and Heavy:
Assault: Charge into the enemies and go havoc with your assault rifle!
Sniper: Experience realistic bullet drops - the further you are from enemies, the higher you should aim for. Plus, maps in WarRock are huge, so you can actually experience true sniping.
Engineer: Don't let the name fool you. Engineer can fix damaged tanks, jets, or warships and turn the tide of the war!
Medic: Heal yourself or teammates so your team can take charge.
Heavy: Destroy everything! You are the one with a bazooka - have fun.

The game is free to play with very low system requirements!
