About

Corefall

Features
Read full description

Corefall is a sci-fi tower defense game about holding colony cores while alien waves push through hostile planets. Build and upgrade towers, trigger command abilities, earn Star Credits, and decide where to spend resources between waves. Each planet changes the pressure with new lanes, enemy types, hazards, and unlock goals. DEFEND THE CORE Place laser turrets, plasma cannons, shields, mines, drones, and orbital tools along winding paths. Keep the core alive as each wave grows faster and tougher. UNLOCK PLANETS AND UPGRADES Survive Mars Outpost, push into frozen moons, jungle worlds, asteroid mines, toxic swamps, crystal worlds, and the alien homeworld. Research stronger tower tiers and finish upgrade timers between missions. COMMAND ABILITIES Use orbital strikes, emergency shields, freeze blasts, repair drones, decoys, and powerful drops when a wave starts breaking through. EARN STAR CREDITS Win waves, claim mission rewards, and use rewarded ads for bonuses such as credits, continues, and upgrade timer skips. Corefall is built for quick strategy sessions with escalating goals, compact maps, and steady tower-defense progression.
