And the best part? A free demo is available now on Steam.

Build. Blast. Repeat.

In TerraTech Legion, you play as a tech pilot deployed to stop the rogue Legion AI from turning the galaxy into scrap. Using Payload’s signature block-based construction system, you’ll craft customizable combat vehicles stacked with everything from cannons and railguns to speed boosters, armor plating, and even laser swords.

It’s not just about slapping parts together, either. Every piece you choose affects your speed, handling, firepower, and survivability as you survive ever-escalating waves of enemies and take down massive AI bosses.

Expect roguelite progression, meaning each run brings new upgrades, unlocks, and brutal build combos to test. Whether you’re plowing through hordes or tactically dismantling enemy formations, every scrap you collect gets you closer to humanity’s last stand.

Key Features:

• Roguelite Vehicle Building – Construct the ultimate combat rig using modular blocks, auxiliary tech, and ridiculous weaponry.
• Bullet Heaven Combat – Face overwhelming waves of mech enemies in high-octane, top-down shootouts across a variety of biomes.
• Physics-Based Mayhem – Turn your ride into a wrecking ball with physics-driven ramming and responsive vehicle handling.
• Upgrade & Evolve – Unlock new blocks, terrains, and strategies with each successful run. Experiment, rebuild, and push deeper into Legion territory.
• Hazardous Biomes – Battle across unique environments packed with deadly terrain and biome-specific threats.

“TerraTech Legion builds on the vehicle-building gameplay our passionate community has loved for nearly a decade, and combines it with a frantic action experience for a match made in bullet heaven,” said Russ Clarke, Co-Founder of Payload Studios.

Whether you’re a longtime TerraTech fan or just love the sound of bullet-spewing custom deathmobiles, now’s the time to jump in.

The demo for TerraTech Legion is available now on Steam—download it, wishlist the game, and get ready to build your way through a robot apocalypse.
