Payload Studios takes the construction-heavy sandbox foundations of TerraTech and pushes them into entirely new territory with TerraTech Legion, a survivors-like roguelite that immediately stands apart from the crowded field through one deceptively simple idea: every upgrade physically changes your vehicle. While countless games have chased the Vampire Survivors formula over the past few years, few feel as mechanically distinct as this. Rather than controlling a lone character weaving through projectile storms on foot, TerraTech Legion transforms the genre into a chaotic vehicular warzone where survival depends just as much on engineering as it does on positioning and reflexes. The narrative framework is intentionally minimal, built around hostile AI swarms overrunning planets, but the game wisely keeps the focus on experimentation and escalation instead of lore-heavy storytelling.
The opening hours can be slightly awkward because TerraTech Legion controls unlike almost anything else in the genre. Steering a modular vehicle through enormous enemy swarms takes time to adjust to, especially when momentum, turning radius and weight distribution begin influencing how effectively your machine handles under pressure. Once the controls click, however, the game becomes remarkably satisfying. Levelling up rewards players with new blocks, weapons and support systems that can be physically attached to the chassis piece by piece, creating an addictive loop where every run evolves into a bizarre rolling death machine assembled through constant improvisation. Clever placements matter enormously too – mounting guns at the rear to protect your blind spots or balancing heavy weapons to avoid tipping over becomes just as important as raw firepower.
That building system is easily TerraTech Legion’s greatest strength because it consistently encourages creativity without overwhelming players with unnecessary complexity. Weapons, wheels, drills, lasers, boosters and utility parts all carry different shapes, weights and connection points, meaning builds naturally evolve according to both opportunity and necessity. At first, it is easy to throw together ridiculous contraptions with little thought behind them, but longer runs gradually reveal how strategic the construction system really is. A badly balanced machine can lose traction, struggle with steering or even topple over during high-speed manoeuvres, while efficient builds begin carving through enemy hordes with terrifying effectiveness. The physics system does a tremendous amount of heavy lifting here because the vehicles genuinely feel like assembled machines rather than cosmetic upgrade trees bolted onto a survivors template.
The variety between characters and progression systems helps reinforce the long-term appeal. Each jockey comes with their own starting Tech and signature abilities, encouraging different approaches to combat. Mikela leans into stunning enemies and manipulating upgrade rolls, Jean-Pierre focuses on aggressive impact-based survivability, Simon emphasizes phasing and critical damage, while Cepheid introduces more evasive movement options. Not every character feels equally balanced, and some builds clearly emerge as more effective than others depending on the difficulty level, but the diversity still helps prevent runs from becoming too repetitive. Permanent unlocks and skill trees also provide a steady sense of progression between attempts, while the eventual unlock of endless survival mode gives dedicated players an opportunity to push absurdly overpowered builds to their limits.
Combat itself delivers exactly the kind of escalating chaos the genre thrives on. Massive enemy swarms flood the battlefield while automated weapons erupt in every direction, turning successful builds into rolling fireworks displays of bullets, lasers and explosions. Yet despite the sheer amount happening on-screen, TerraTech Legion generally remains readable and surprisingly tactical. Weapon arcs, firing directions and blocked lines of sight all matter, meaning efficient construction directly affects combat effectiveness. Boss fights and enemy bases also add welcome pacing shifts beyond simple crowd-clearing, although certain encounters expose some frustrating balance issues. A few bosses absorb damage for far too long, while others can pin players into awkward positions capable of instantly ruining otherwise promising runs. Difficulty spikes can therefore feel harsher than expected, especially early on before upgrades and stronger unlock pools begin smoothing things out.
On PlayStation 5, TerraTech Legion presents itself cleanly despite the constant visual chaos. The colourful sci-fi aesthetic works well with the modular building concept, and watching increasingly ridiculous vehicles tear through hordes of robots carries an undeniable sense of spectacle. The interface is intuitive enough to keep vehicle customization manageable even mid-run, which is crucial given how frequently adjustments happen during play. Performance generally holds up well despite the density of enemies and effects, and the responsive controls help the game retain its fast pace even during particularly hectic encounters. Audio design complements the action nicely too, with crunchy explosions, satisfying weapon effects and energetic synth-heavy music helping reinforce the game’s momentum without becoming overbearing.
What ultimately makes TerraTech Legion so compelling is how naturally it blends construction mechanics with the survivors formula instead of treating the building system like a gimmick. Every successful run feels partially authored by the player because every strange shape, unbalanced monstrosity or finely tuned death machine emerges through personal experimentation. It occasionally lacks the sheer mechanical depth or build complexity of the absolute best games in the genre, and some balancing frustrations still need refinement, but Payload Studios has nevertheless created one of the more inventive survivors-likes in recent years. On Xbox, TerraTech Legion delivers a chaotic, addictive and consistently entertaining blend of engineering sandbox and bullet heaven action that feels genuinely fresh in an increasingly crowded space.
Score: 8.3/10
