How co-op works
Up to four online players join Recovery Day or Endless defenses around one mobile outpost. Teams explore and gather components, strengthen automated fortifications, wield XEN firearms, and coordinate field combat as the base faces extraction sieges or infinite waves.

The core loop mixes firefights with resource collection and tactical fortification. Players gather unique Weapon Units to amplify their Outpost's firepower, coordinate defensive layouts, and adapt loadouts between waves. Success depends on dividing responsibilities and communicating which upgrades to prioritize as enemy pressure escalates.
Online co-op transforms each session into a communication-heavy operation where base management and FPS reflexes matter equally. Teams must balance offensive scouting runs with defensive preparations, making every role count. The genre fusion creates sessions that reward both tactical planning and sharp shooting.

Frequently Asked Questions
Is this more of a shooter or a tower defense game?
It's a genuine hybrid. You'll be shooting enemies in first-person while also placing defenses, upgrading your Mobile Outpost, and managing resources between waves. Both your aim and your strategic planning matter equally.
Do we need voice chat or good coordination to play co-op?
Yes, communication is key. The game is described as communication-heavy teamwork where you'll need to coordinate who handles offensive scouting, which defenses to build, and what upgrades to prioritize as enemies get tougher. Playing with friends who can talk through strategy will make a big difference.
Can I play this solo or is it co-op only?
The game supports both single-player and online co-op. You can tackle it alone if you prefer, but the co-op mode lets you split responsibilities like base defense and resource gathering with teammates.
