Thanks. Can't you throw shields or ammo out or something too?
Nope.. Shields are another Class, and so is ammo.
And you use R1 to drain energy from your enemy(Also restores your health) and then R2 to shoot the ball at teammates to heal them.
Medics can unlock secondary weapons(Press triangle to switch) after I think level 3.
Solder-R1 is a Machine Gun and R2 is the shield.
Soldiers lead the charge into battle and provide cover for allies. They earn points by damaging enemies and by absorbing damage with their force barriers. They cannot succeed without the help of the other two classes.
Medic-R1 is Drain, R2 is to heal teammates.
Medics are able to turn damage dealt to enemies into health they can give to allies. A medic gains points by damaging enemies as well as healing and reviving allies. Good medics are the most valuable players in the game
Spec Op-R1 is a High Powered Sniper, R2 gives special Ammo.
Spec Ops Commandos inflict heavy damage and provide ammo for the rest of the team. They earn points by damaging enemies and creating ammo for allies. Missions hinge on the spec ops players keeping the team stocked with ammo.
