You play as a Tech jockey taking on waves of AI-controlled robots across four planets. Each run puts you behind the controls of a combat vehicle that you assemble from blocks.
Fit your rig with weapons, wheels, boosters, and utility parts, then reshape it as you acquire more blocks during a run. Combat combines automatic firing with driving, positioning, aiming, and timed boosts as you fend off enemy swarms and face bosses.
Four characters offer different starting vehicles and playstyles, while four corporations provide distinct blocks and abilities. Complete missions, upgrade skills between runs, and take on planetary bosses; an endless mode challenges you to last as long as possible.
Players who enjoy the game often point to its vehicle-building loop: arranging weapons and parts makes each run feel different, and some find the combination of driving and combat more engaging than simply moving through enemy waves. A recurring criticism is that randomized part choices can make it difficult to shape a desired build, while progression and difficulty may feel grindy or frustrating. Some reviewers also cite awkward vehicle handling, getting caught on terrain, or repetitive runs.
A swarm of AI bots is tearing across the galaxy, assimilating everything in its path. As a maverick Tech jockey with nerves of steel, it's on you to clean up the carnage. Build something fast enough, mean enough or heavy enough to push back, then smash it all into scrap.
TerraTech Legion is a bullet heaven from Payload Studios, the team behind the original TerraTech. It takes the block-based vehicle building the series is known for and drops it into a roguelite full of swarms, bosses, and bad ideas worth trying.
With 200+ blocks across weapons, propulsion and utility, there’s no shortage of wild ideas that just might work. Wheels, boosters, buzzsaws, orbital lasers - snap them together however you like. Each of the four TerraTech Corporations brings its own set of blocks and abilities to the table, so your starting point shapes what you build and how you fight.
How it all comes together is up to you. Stack on the weapons and you're a rolling gun platform. Go heavy at the front and you're built to ram. Pile on the boosters and you're fast, fragile, and hard to catch. Where you put things matters - weight, balance, and whether you can actually steer it all come into play.
Jean Pierre hits hard and keeps on hitting - built for impact and impossible to slow down. Mikela plays the odds by stunning enemies and rerolling her luck until the rarest blocks fall her way. Sam phases through enemies and doubles down with critical hits. Cepheid drifts through the battlefield leaving a trail of plasma in her wake. Each character comes with their own starter build and playstyle - find the one that fits how you fight.
Four distinct planets, each crawling with bots, outposts and factories, all building to a brutal planetary boss. Upgrade your skills between missions to up your game and bring the fury on each new run.
How long can you last? Drop into an endless onslaught of Legion bots and bosses with no checkpoints, no campaign and no way out. Just you, your build, and your high score.
