Classes

The game is class-based, with players choosing from the roles of Officer, Special Weapons, Medic, and Tech. Each class has two selectable characters with a difference in abilities.

Officer
Grants a passive bonus to damage and defense resistance to nearby allies. He has access to a class-restricted shotgun with an incendiary grenade launcher and has general all-around abilities. They are also capable of throwing extra amounts of explosive ordnance, and may find class-restricted ammo caches on the field for his Vindicator shotgun. The two playable characters are Sarge and Jaeger.

Special Weapons
Brings raw damage to the table and starts out with a customized autogun with superior parameters, high magazine capacity, and auto aiming ability. The Special Weapons gains access to a powerful minigun at a high enough level, and can pick up class-restricted ammo caches on the field. The two playable characters are Wildcat and Wolfe.

Medic
Is able to equip and deploy temporary healing beacons, and at a high enough level can use a "healing gun" to selectively heal teammates and themselves. The two playable characters are Faith and Bastille.

Tech
Carries a motion sensor, can set up sentry guns faster, welds doors faster, and is the only class capable of unlocking certain door panels or completing certain objectives by means of a hacking minigame. They also have access to a prototype assault rifle with auto aiming capabilities and the ability to fire stun grenades. The two playable characters names are Crash and Vegas.
