About OneForAll

OneForAll is a post-apocalyptic zombie game in which you play as one of the last survivors. After a government project called Project X collapses, the creatures it studied spread across the world. You explore the open world, take on quests and try to defeat the zombies, with the possibility of restoring peace.

Project X

Project X began after strange creatures were found beneath the country's territory. A secret government operation captured many of them for study. The creatures proved to be a new species resembling humans, but with a rare genetic mutation called the “X” gene that leaves them unable to feel fear or pain. The government planned to use them as slaves for protecting the state, building weapons and other work requiring courage and strength.

The government later collapsed, leaving the project abandoned. The scientists disappeared and eventually became part of the strain, which spread globally.

Explore and progress

OneForAll has a single-player exploration mode, an inventory, and quest and level systems. Its open world offers many possible things to do.
