About this game
YOUR TIME IS RUNNING OUT
Antidote is a high-tension roguelite FPS. You have been infected. The virus is already pulsing through your veins, and every heartbeat brings you closer to transformation. Your only hope? Descend into the depths of a massive bunker to find the antidote and inject it before it’s too late.
KEY FEATURES
- Race for Life : Here, escaping isn't enough. You must explore the bowels of the complex to locate the cure. Manage your progress carefully: every detour for resources is a risk that could push your infection gauge to the point of no return.
- Survival Missions in Hostile Environments : Explore a vast, ever-changing bunker where every mission is a key to your survival. To navigate this procedural labyrinth, you must master the complex's systems: restore power to pitch-black sectors, secure infested zones, or unlock critical access points. Completing your objectives isn't an option—it's the only way to reach the antidote before time runs out.
- Brutal Combat and Assassinations : Facing a diverse horde of zombies, combat is a necessity. Utilize a hard-hitting arsenal and take advantage of a detailed assassination animation system to eliminate threats with precision. Every bullet counts, and every execution buys you precious time.
- An Unpredictable Bunker : Thanks to procedural generation, the layout of the bunker, the position of resources, and the infected change with every run. Adapt or transform.
- A Diverse Arsenal : Master a wide range of weapons, from brutal melee tools to powerful firearms. Every tool is essential to adapt to the different threats lurking in the bunker. Manage your ammo, choose your firepower, and unlock devastating gear to carve your path to the antidote.
