Set in a gritty, fictional 1960s universe, it’s a colony sim & base-building hybrid where you rebuild a war-ravaged region, fortify your defenses, and control key trade routes that every convoy depends on.
Border Base
Steam
Step into the gritty 1960s and prepare to command, rebuild, and defend your own strategic military outpost in Border Base, a thrilling colony-sim, base-building, and grand strategy hybrid. Inspired by genre-defining hits like RimWorld and Oxygen Not Included, Border Base thrusts you into a dynamic, war-ravaged region that desperately needs your leadership.

From the very start, Border Base breaks away from traditional base-building games—forget the quiet, safe corners of a map. Here, international convoys and trucks rumble straight through your territory, placing you at the center of geopolitical tension. Every decision you make ripples outward, impacting not only your base but the fate of nations around you.
