The Khyr have taken the outer colonies. Earth is next. Build towers, study each wave, and stop new enemies in every level.
Watch real gameplay from level 5, Colony Ship Exodus. Check the routes, build towers, start waves at 2x speed, and fight Hullripper.
Recorded on a phone from the current game.
Every act ends with a unique boss. Hullripper disables towers and summons Skitterlings. The Choir's three sisters slow towers, heal allies, and make the swarm faster. Each boss needs a different strategy.
Use the right strategy to defeat each boss.
Tap a boss during the fight to see its stats, abilities, and weaknesses.
Armor reduces damage from bullets. Shields resist beams. Some enemies teleport or go underground. Choose the right towers and positions.
Levels take 8-15 minutes. Waves start automatically, and you can use 2x or 3x speed. The game works fully offline.
Preview attack routes before a level. See tower stats before you build. Tap any enemy to see its stats, abilities, and weaknesses.
Freeze all enemies, drop meteors, or hit strong enemies with orbital beams. All superweapons share one charge, which refills slowly.
Fight from the outer colonies to the Overmind's homeworld. The 6 acts have different maps and enemies.
Choose Easy, Normal, or Hard. Earn stars and improve your campaign score. Level 1 includes an interactive tutorial.
Each tower is strong against different enemies. The upgrade to level 4 offers two paths. Even the first Pulse Turret stays useful in Act 6.
