Creeper World 4 (Steam)

The eternal harvester of galactic empires has returned! Witness massive waves of Creeper flood across the 3D terrain in this real time strategy game where the enemy is a fluid. Build out your economic base with energy and mined wares. Assemble your forces and struggle against the creeper on all fronts as it floods and fills the map. Take the high ground with your forces to avoid the creeper as waves crash around your base. Increase your lines of sight and range on high ground, but beware the aerial units. And, if you last long enough, launch orbital weapons and call down devastating strikes on the enemy.
