About Biotoxin: The Dark Days
Biotoxin: The Dark Days is a horror platform shooter set in post-apocalyptic America in 2048. In a biological war, most of the world's population was either wiped out or weaponised. Seventeen years later, you travel across the ruins, scavenging for supplies and fighting to survive.
Explore and scavenge
You move through environments ranging from small towns and forests to dense cities, using your wits and skill to get past infected people and other survivors. Loot buildings and levels for food, ammunition, weapons and medicine; you need supplies to survive.
Fight to survive
Combat against the infected and humans is fast and frantic. You use your weapons and the environment to survive encounters. The arsenal ranges from crude melee weapons to military firearms.
Game modes
Play through 10 large levels in the post-apocalyptic story, or test your skills in horde mode.
