About Iron Reactor

THE REACTOR HAS GONE SILENT1989. For 43 seconds, a secret Soviet reactor produces an impossible surge of energy. Then all contact is lost. Captain Alexei Morozov reaches ZHELEZO alone, with orders to recover the research data and shut down the reactor. Beyond the military checkpoints, something is changing the workers, the machinery and the facility itself. STEEL, RADIATION AND SOMETHING BEYONDIRON REACTOR is a single-player retro FPS built on its own raycasting engine. Fight through military bunkers, laboratories and industrial halls as familiar surroundings give way to organic growths and an alien reality.

Dodge projectiles, manage ammunition and armor, and watch your step: contaminated floors and radioactive clouds can turn a victory into another hazard. Recover every terminal's data and eliminate every enemy before the exit opens. Your health, armor and ammunition carry into the next campaign level, so what you leave a sector with matters as much as how you clear it.YOUR MISSION24 campaign levels across four acts, from Soviet military installations to the other side of the reactor. Seven weapons: pistol, Iron Maw shotgun, assault rifle, resonance launcher, double-barrel shotgun, machine gun and railgun.

15 enemy types, including mutated soldiers, radioactive experiments, machine-organism hybrids and five bosses. Six difficulty settings, with tougher enemies and increasingly punishing attacks. Survival mode with growing enemy waves, boss encounters and personal records. Research terminals, supplies and radioactive hazards throughout the campaign. Customizable weapon definitions in JSON: damage, ammunition and sprite references.…
