Overview
Thousands of rift creatures. One base. Aim every turret's line of fire, then take the main cannon into your own hands. Take down five bosses across 15 maps, grow stronger between runs, and climb the global leaderboard in Endless. Build and share your own maps on the Workshop.
Description
The rifts are open. Thousands of creatures pour down the paths toward a single base, and you decide where every line of fire goes.
Turrets here don't just shoot whatever wanders into range. You place each one beside the road and set its angle, so a shot that rakes along the path pierces the whole column. Nine turret types, each with its own way of killing:
One cannon sits on your base and covers the whole map. Aim with the mouse and fire. Switch between five shells, from high explosive and armor-piercing to a focus beam that burns hotter the longer you hold it. Three combat skills cover the moment the line breaks.
Fifteen maps across five regions, and every region ends with a boss that changes as it falls. Bosses call in fresh swarms, empower the creatures around them, tear open new rifts, or hide behind armor plates you have to break first.
Win or lose, you keep what you earn. Level each turret from 1 to 8 and pick a fork at levels 3 and 7, then swap forks for free between maps. Raise the cannon and the skills, and buy Sigil Engravings that change how things work. Switch on any of eight risk modifiers when you want more income for more danger.

Endless mode never stops growing. Boss picks reshape your build mid-run, a refit between waves lets you adjust, and a global leaderboard ranks your score, wave and kills.
Draw the paths, drop the rifts and the base, set the rules and test-play in seconds. Share a map as a short code or on Steam Workshop, and play what other defenders build.
