Unlike the original Mass Effect, where weapons overheat if fired continuously for prolonged periods, the weapons of Mass Effect 2 have a finite magazine and must be reloaded after a certain number of shots.
Ao contrario que no seu predecesor Mass Effect, onde as armas sobrequencíanse ao ser disparadas de forma continua nun período de tempo prolongado, as armas en Mass Effect 2 teñen un cargador finito e deben recargarse tras un determinado número de disparos.
