Leveling up is achieved by killing enemy soldiers.

In the works is an actual experience bar and a buy system, but that may be some time yet before it will show up in a future release. For now, you unlock secondary attacks on your weapons:

Pistol - fast attack, empties remainder of magazine at once
Assault rifle - rifle grenades, uses grenade ammo
Shotgun - powershot, consumes more ammunition, slower cooldown.
