Assault on the Demonic Realm: A Retro-Inspired FPS

Assault on the Demonic Realm is a fast-paced boomer shooter that drops players directly into the center of a hellish invasion. This free-to-play first-person action game pairs relentless combat with old-school level design inspired by 90s classics.

Developed by Studiohammergames, this Unity-engine title offers a highly challenging experience right out of the gate. Players spend their time fighting through genuinely grim locations. You push past ancient fortresses and nightmarish temple ruins, dealing with whatever the system spawns in your path. And it spawns a lot. The enemy roster ranges from basic demonic minions to massive behemoth monsters. Each creature operates with distinct behaviors and attack patterns. This forces you to constantly shift tactics rather than simply holding down the fire button and hoping for the best.

Combat heavily mirrors the speed and aggression of the Quake franchise. Mobility is your absolute best survival tool here. Players have access to a heavy arsenal of firearms alongside brutal melee attacks for when enemies close the gap. Standing still usually means a quick game over—especially during punishing environmental hazards like the spinning bridge section. The difficulty spike is real, demanding quick reflexes if you want to clear the later stages.

Visually, Assault on the Demonic Realm handles itself well for an independent release. The 3D graphics pull more weight than you might expect, creating a dark, atmospheric setting that feels right at home in the retro horror space. It also runs smoothly across both HTML5 browser sessions and Windows downloads. Performance stays surprisingly stable even when the screen is completely crowded with monsters.
