A reactor core and a defense tower facing a violet rift on a dark volcanic world
Rift Defense

Something is coming through the rift on Eos-7.

A 3D tower defense game for Android. Build along the route, stop 15 waves and keep the core alive.

Coming soon to Google Play
Three upgraded towers beside the route in the game

The Prism Behemoth, a boss covered in violet crystal, on the route

Ten creatures and three bosses

Shields, splitters and sprinters all break a plan in different ways. From wave 6 a second route opens, and from wave 11 a third.

  • Rift Maw Wave 5
  • Prism Behemoth Wave 10
  • Breachkeeper Wave 15
A wave of creatures walking the winding route toward the core

No two runs play the same

Between waves, pick one of 20 upgrades to shape your defense. In a crisis, Commander Astra can call an Orbital Lance or slow a whole area with a Time Anchor.

Win or lose, you earn Alloy for permanent upgrades. Close the game mid-mission and continue from the last wave you cleared.
