Read full description

Outpost Frontier is a compact sci-fi strategy game about surviving beyond the safe perimeter. Sweep the radar to find limited-time missions, choose the contact you want to risk, then send your squad into tactical encounters against crystal-machined threats. Bring the rewards home, expand the base, upgrade your command tower, and push your squad power higher for deeper runs. Every session gives you a clear choice: scan, fight, build, upgrade, or stockpile resources for the next push.
