OuterRealm

OuterRealm is an old-school FPS in which you play as an elite soldier wearing ironclad atomic power armor. You collect powerful weapons, fight waves of voidborn horrors, and enter realm portals to defeat their demigod masters.

Fight and explore

Collect items, unlock upgrades, kill bosses and find exits. You can also play in endless mode. The oversized weapons include a flak cannon that doubles as a close-combat hammer, overheated guns that fire blasting bullets, and a giant sword for cutting through aliens. Weapons deal brutal elemental damage, and combat skill helps keep the monsters at bay.
