The weapons from the Combat Universe, available for many types of infantry, form the main damage counters.
Scorpion weapons tend to use bullets, explosives, rail guns, and lasers. Spiker weapons are generally plasma or energy based. All plasma weapons use charge. All weapons run out of ammunition or charge when used extensively. Covenant weapons typically overheat if fired continuously for long periods of time, which causes your weapon to become temporarily unresponsive.
