7 Days to Die is a massive open-world game that uniquely combines first-person shooting, survival horror, tower defense, and role-playing. Players must scavenge, craft, and build a base to survive in a world overrun by the undead, which become significantly more aggressive every seven days. The fully destructible environment allows for creative building and complex traps to fend off the massive zombie hordes. It features a deep progression system where every action improves your character's ability to stay alive in the apocalypse.
