Recon: Largely the standard class from the base game, but has access to the /totalb command, which tells you how many bots are left alive and how many reinforcments remain.

Specialist: Has access to some unique secondary weapons.

Rifleman: A secondary assault class with access to improved armor in comparison to most classes. Also has access to a wide variety of assault and battle rifles.

Heavy Unit: A high survivability class with access to the heaviest armor available to any class.

Signaller: Can use a signal flare to call in reinforcements. (Revives entire team)

Designated Marksman: Access to DMRs and other, non-bolt-action precision weapons.

Sniper: Access to precision weapons including bolt-action rifles.

Breacher: Has access to a variety of weapons, most noteworthy of which being several shotguns and the riot shield secondary weapon. The riot shield can be used to tank small arms fire from the front.

Support: Has access to all LMGs, and sole access to GPMGs.

VIP: Has access to 2 secondary weapons (no primary) and a special VIP-only armor. The friendly team also earns supply points if the VIP survives a set amount of time. But be careful, as if you die as the VIP, you will respawn the enemy team. (Additionally, VIP can't respawn from friendly flares.)

Spy: As the spy you can wear enemy armor, and, in doing so, you have a 20% chance of not being shot at if a friendly is nearby. However, this comes with the tradeoff of potentially having your team mistake you as an enemy and teamkilling you. The Spy also has access to several unique weapons.

Suicider: Has the ability to explode himself. Do this by binding a key by typing "bind [key] suicide" in the console. Where [key] is whichever key you would like to trigger the self destruct.
