Co‑op Play
Up to six players can team up online, each choosing weapons, armor, and Perks to balance the squad against the monster hordes. The game also offers a solo mode for offline play, letting a single player experience the same wave‑based challenges.
Players can coordinate actions such as welding doors closed to redirect monsters, using medical tools to aid teammates, and sharing equipment like body armor to improve survival chances.
- Communicate door‑welding plans to shape monster paths.
- Distribute medical tools early to keep the team alive.
