Is Biotoxin: The Dark Days worth it for you?

We tell you who should skip it, too.

Play it if you…

Good fit
  • Horror-action players who want a shooter set in a ruined modern world rather than a fantasy setting.
  • Platform-shooter fans who enjoy searching levels for supplies before facing enemies.
  • Players who want both a story campaign and a horde mode rather than only one play format.

Skip it if you…

Saves you a refund
  • Players who want a slow, low-pressure pace may hit a wall when combat becomes fast and frantic.
  • Players who prefer a single uninterrupted campaign may not enjoy switching between the 10-level story and the separate horde mode.
  • Players looking for a fantasy setting may find the post-apocalyptic America setting a mismatch.
  • Players who want a nonviolent game may find its combat against infected and human enemies unsuitable.

Our take on Biotoxin: The Dark Days

The likely bounce point is the combat: encounters are framed as fast and frantic, and survival depends on using weapons and the environment. Players who want a measured pace may hit that wall as soon as enemy fights begin.

What is Biotoxin: The Dark Days?

Set in post-apocalyptic America in 2048, this horror platform shooter follows a survivor travelling through the ruins 17 years after a biological war.

Most of the population has been killed or turned into weapons. Players search buildings and levels for food, ammunition, weapons, and medicine, then use weapons and the environment against infected and human enemies. The campaign has 10 levels and moves through settings including towns, forests, and cities. Its weapon selection ranges from improvised melee arms to military firearms. A separate horde mode offers another way to play beyond the story. Combat is described as fast and frantic, while the environments call for using wits and skill to get past enemies.
