Game Features

Defend the Colony

Proxima Centauri is under attack from hordes of alien invaders! Play through a vast campaign full of challenging missions. Deploy defenses, use powerful orbital abilities, and call units at the right time and place in order to win.

Customize your Defenses

Choose from dozens of tower upgrades and determine what you need in order to survive. Upgrade your particle cannon to slow its target, your Artillery Post to leave fire in areas it has attacks, or your Corrosion Mortars so that victims infect the allies around them.

Fight Against Dozens of Enemies

The alien invaders have many unique attacks and defenses. Beware the Falling Star that disables defenses when it explodes, or the Heart of the Phoenix that forms a chrysalis when destroyed that can be reborn as a new Heart.

Create your own Missions

Use the in-game workshop, then upload and share them with other players. Download new missions created by other users, too. Get started with the Modder's Guide here.

See how long you can survive against relentless enemy waves in Endless Mode! Try to outlast other players and compare your scores on the leaderboards.
