DeepCore Breach

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.

From the Steam store

The rifts are open. Thousands of creatures pour down the paths toward a single base, and you decide where every line of fire goes.

AIM YOUR DEFENSES

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:

Burst and Heavy fire straight through the line, Heavy ignoring armor. Flame, Sear and Seeker burn, beam and chase. Mortar and Corrosion leave fire and acid on the ground. Arc chains lightning through the crowd, Riptide slows it and pulls it together.

TAKE THE MAIN CANNON

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.

FIVE REGIONS, FIVE BOSSES

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.

GET STRONGER EVERY RUN

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.

HOW LONG CAN YOU LAST?

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.

MAKE YOUR OWN MAPS
