TerraTech Legion

 
Payload Studios developed and Mythwright published TerraTech Legion. It launched on April 30, 2026 for PC via Steam, Epic Games Store, and Microsoft Store, and for Xbox Series X/S with Xbox Play Anywhere support. Payload Studios is the London-based team behind the original TerraTech sandbox vehicle builder. Mythwright is the publishing label handling this new franchise direction. TerraTech Legion is available day one on Xbox Game Pass Ultimate and PC Game Pass. It takes the block-based building system the series is known for and drops it into a bullet heaven roguelite structure where building the vehicle is the core gameplay rather than a preparation step.
About the Game
TerraTech Legion casts you as a maverick Tech jockey sent to reclaim planets overrun by The Legion, a rogue AI army assimilating everything in the galaxy. Your only tool is a vehicle you build yourself from modular blocks, then pilot through relentless waves of enemy bots, outposts, and factories. There are no passive level-ups or weapon drops here. Your power comes entirely from how you construct your machine: which weapons you attach, where you position them, how you balance propulsion and utility, and which of the four TerraTech Corporations you build from. Furthermore, runs are distinct from the original TerraTech’s open-world sandbox, placing you in tightly structured wave combat where your build decisions determine your survival far more than reflexes alone.
Building Is the Gameplay
TerraTech Legion provides 200+ blocks spanning weapons, propulsion systems, and utility tools. Wheels, boosters, buzzsaws, and orbital lasers all snap together freely. There are no wrong builds, only builds that suit the current planet better or worse than others. Each of the four TerraTech Corporations brings a distinct block roster and passive abilities to every run. Your choice of starting corporation sets the direction of your entire build path. Furthermore, blocks are added and upgraded mid-run rather than unlocked before it, which means every session begins with a bare chassis and grows into something unique. Consequently, no two successful runs look the same even when played back-to-back.
Four Planets and an Endless Mode
The campaign sends you across four distinct planets, each crawling with Legion bots, outposts, and factories at escalating difficulty levels. Each planet culminates in a planetary boss fight that demands a build capable of surviving sustained heavy assault. Skill upgrades between missions let you tailor your pilot’s capabilities over the course of a full run. Furthermore, once the planets are cleared, an Endless Mode strips away checkpoints, campaign structure, and narrative context entirely. You face an infinite onslaught of Legion bots and bosses with only a high score to chase. Consequently, Endless Mode serves both as a post-campaign challenge and a pure expression of the build system without any other objective in the way.
Caractéristiques principales
Vehicle Building and Corporations

200+ Blocks Across Weapons, Propulsion, and Utility: The full block roster covers every function a combat vehicle needs. Weapon blocks span close-range options like buzzsaws up to long-range orbital laser systems. Propulsion blocks include wheels of varying grip and handling profiles alongside boost systems that change your vehicle’s speed and manoeuvrability. Utility blocks add armour, shields, and supplementary systems. Furthermore, all blocks snap together freely without a fixed template, so the vehicle shape is entirely your decision rather than a choice between preset loadouts. As a result, the build system rewards experimentation over following an optimal path, and discovering a combination that works is a genuine reward in itself.
Four TerraTech Corporations with Distinct Block Sets: Each of the four Corporations defines not just which blocks you start with but which blocks you can add during the run. Every Corporation has passive abilities that interact differently with the wave combat structure. Starting as one Corporation and then starting again as a different one produces a genuinely different run experience rather than a cosmetic change. Furthermore, learning the strengths and weaknesses of each Corporation’s block set and matching them to each planet’s enemy composition is a layer of strategic depth that sits above the moment-to-moment building decisions. Consequently, mastering all four Corporations is the long-term learning curve TerraTech Legion provides beyond simply completing the four-planet campaign.

Roguelite Progression

Skill Upgrades Between Missions Build Run-Specific Pilot Power: Between missions, a skill tree lets you select upgrades that accumulate over the course of the current run. These upgrades affect how your pilot interacts with the vehicle and the environment rather than permanently altering your block roster. Skills are lost at the end of a run, preserving the roguelite structure where each attempt starts fresh. Furthermore, the upgrade decisions you make between planets shape whether you focus on survivability, firepower, or mobility, giving the skill layer a different strategic axis from the block building layer. As a result, strong runs involve good decision-making at the build screen, the skill screen, and in the field simultaneously.
Endless Mode with No Checkpoints and High Score Chasing: Endless Mode is a permanent fixture accessible outside the campaign at any point. It drops you into a continuous onslaught with no mission structure, no planet progression, and no checkpoints. The only metric is how long you survive and how high your damage score climbs. Furthermore, Endless Mode removes the pacing breaks the campaign provides, which makes build quality and vehicle coherence the absolute deciding factor with no skill upgrades or mid-run checkpoint recoveries available. Consequently, Endless Mode functions as the game’s purest mechanical test and its most replayable format once the campaign planets are cleared.

Planets and Combat

Four Planets Each Built Toward a Planetary Boss: Every planet has its own enemy type density, outpost layout, and factory configuration that favours different builds over others. The escalation within each planet moves from manageable swarms toward elite-tier bots and finally the planetary boss. The boss fights require sustained output and survivability from your vehicle rather than a short burst of peak performance. Furthermore, the enemy variety reviewers praised in early coverage highlights how each planet functions as a distinct combat environment rather than a reskin of the same wave structure with higher numbers. As a result, clearing all four planets on higher difficulties is a meaningful challenge that rewards build knowledge accumulated across multiple previous run attempts.
Bullet Heaven Structure with Swarms, Ramming, and Infinite Projectiles: TerraTech Legion sits firmly in the bullet heaven genre alongside Vampire Survivors and its contemporaries, but replaces the passive character-level upgrade loop with active vehicle construction. Enemies swarm from all directions, and survival involves both shooting at range and ramming bots at speed when they close the gap. The infinite projectile style means late-run builds generate enormous amounts of visual chaos on screen as weapons fire continuously without ammo management. Furthermore, the sheer volume of enemies that appear simultaneously was specifically noted by reviewers as one of the game’s most impressive technical achievements. Consequently, well-constructed builds feel dramatically powerful in a way that directly rewards the time spent at the build screen.

TerraTech (Original)
The open-world sandbox predecessor from the same developer. It uses the same block-based building system but in a free-roaming exploration and crafting structure rather than a bullet heaven roguelite. There are no wave runs or roguelite progression loops. Furthermore, the original TerraTech has a far larger block count, a full campaign, and years of DLC content. It is a complete and fully released game with a much longer playtime ceiling than Legion at its current price.
Players who want the full-scale TerraTech open-world sandbox experience with deep crafting, base building, and exploration rather than the focused roguelite wave combat structure of Legion.


Survivants du vampire
The genre-defining bullet heaven title that TerraTech Legion draws direct structural inspiration from. However, it uses a simple 2D pixel art character rather than a fully constructed modular 3D vehicle. There is no build system and no vehicle construction layer. Furthermore, it is available at a lower price point and has a vast catalogue of characters, stages, weapons, and DLC content accumulated over several years of post-launch support.
Players who want the most content-rich and fully developed bullet heaven experience at the lowest price, without the vehicle building layer that TerraTech Legion adds on top of the genre template.


Brotato
Also a bullet heaven roguelite with a large weapon variety and wave-based structure. However, it uses a top-down 2D format with a small potato character rather than a 3D modular vehicle. Weapon selection is menu-based rather than physically constructed block-by-block. Furthermore, Brotato has a much larger character and weapon roster with distinct starting builds that function more like class selection than TerraTech Legion’s freeform construction approach.
Players who want a bullet heaven roguelite with the widest variety of starting character builds, a large active community, and a fully developed content slate rather than the physical vehicle building hook of TerraTech Legion.
