- Fire in bursts while watching its charge.
- Shoot scenery that may hide supplies.
- Use a bomb when several attackers close in.

Alien3: The Gun (US, Rev A) — About this game
Alien3: The Gun (US, Rev A) places a positional Pulse Rifle in a rail-shooting escape from an alien-infested facility. Continuous fire drains its charge and forces a recovery interval, while a separate limited bomb attack clears approaching aliens. Shooting scenery can uncover supplies and a temporary flamethrower. Prisoners encountered along the route add a reason to distinguish survivors from targets during the automated advance.
