Orbital Colony: Swarm Protocol

About Orbital Colony: Swarm Protocol: Sci-Fi Idle Defense and Action Strategy

Orbital Colony: Swarm Protocol drops you into command of a fortified colony under relentless alien assault. The game blends idle defense with active action strategy, asking you to balance tap-to-attack combat in the heat of each wave against the slower, persistent work of upgrading weapons, production, and research over time. Several scenes show small red, green, and purple thin-legged creatures with white rectangular tops arranged in large clusters across the gray field. A large black and teal cylindrical structure with four protruding white blocks sits on the lower-left side of the play area in multiple views.

How to Play Orbital Colony: Swarm Protocol: Defend, Upgrade, and Survive Every Wave

The goal is to defend the orbital colony and survive every enemy wave. Click or tap enemies directly to deal damage, then spend earned resources on upgrading your tower and robotic troops between engagements. When the swarm grows overwhelming, deploy tactical spells to turn the tide. Drag deployable abilities onto the battlefield where prompted. Clear all waves and defeat the boss to win the level. Persistent progression, research timers, and optional rewarded bonuses carry your colony's growth forward across sessions.
