EVERY COLONY HAS A BREAKING POINT

Stelvyr: Colony Defense is a colony-building and defense strategy game set on a hostile planetary frontier. Every structure, crew member, and unit of power can determine whether your colony survives.

Establish production, route a limited power supply, deploy specialist crew, and shape your defenses before alien swarms attack from multiple directions. When the battlefield changes, your strategy must change with it—no single defensive plan can win every operation.

BUILD A COLONY THAT ACTUALLY WORKS

• Manage critical resources — Produce Minerals, balance Power, and maintain enough Crew to keep essential systems operational.

• Command physical crew — Engineers, Gunners, Scientists, and Xenobiologists travel to their assignments, repair damage, rescue casualties, and risk their lives in the field.

• Shape the battlefield — Combine walls, gates, turrets, mines, and orbital weapons to create defensive lines suited to each approach.

• Choose your discoveries — Research technologies that transform your economy, power grid, and combat capabilities.

READ THE BATTLEFIELD. ADAPT THE COLONY

Every hostile species plays a different role. Some assault the colony directly, while others break fortifications, sabotage the power grid, support nearby swarms, or pressure vital infrastructure.

Orbital conditions, mission events, and adaptive reinforcements punish static plans. Monitor the radar, study incoming waves, reposition crew, reroute power, and reinforce weaknesses before they become disasters.

NINE OPERATIONS. THREE DIFFICULTY LEVELS

Fight through nine campaign operations, each with its own rules, starting conditions, strategic objectives, and signature threats.

• Cadet — Learn the colony systems and experiment with different defensive strategies.

• Commander — Balance expansion, research, staffing, and defense under sustained pressure.

• Veteran — Face tighter resources, more dangerous enemies, and consequences that leave little room for error.

Build. Plan. Adapt. Hold the colony until the final wave.
