TerraTech Legion keeps its long term goals in plain sight: planets to clear on rising difficulty, stars to collect, drivers to max out and an endless mode to set scores in. The official achievement list spells all of it out, so this page organises it into a plan. Background on stars and objectives comes from Roundtable Co-Op, and everything else from the store page and the achievement list.

1 Planets and difficulty

The store describes four distinct planets, each crawling with bots, outposts and factories and building toward a planetary boss. The achievement list names them and adds three difficulty levels for each, with the achievement names using Easy, Medium and Hard.

PlanetAchievements
DustbowlEasy, Medium, Hard (levels 1 to 3)
Rotwater BasinEasy, Medium, Hard (levels 1 to 3)
Icebound HollowEasy, Medium, Hard (levels 1 to 3)
Magma HellscapeEasy, Medium, Hard (levels 1 to 3)

That is twelve completion achievements in total. Clear every planet on level 1 first so that stars and skill tree upgrades accumulate before you try the harder levels.

2 Stars and objectives

Roundtable Co-Op explains that stars come from objectives, such as destroying a set number of Legion outposts or taking down a planetary boss mech, and that stars unlock new planets. TheSixthAxis adds that some objectives ask you to use particular characters. The All Star achievement asks for all 48.

Read the objectives before a run
Because objectives can require a certain driver or target, pick your driver after reading them. It saves replaying a planet just to collect one missing star.

3 Drivers and skill trees

Cepheid SwanBetter Future Feature / Swan Song

Player level milestones also appear: Not bad at level 20, Oh! at level 25 and AHHH! at level 30.

4 Corrupted blocks

Ten achievements ask you to attach a specific corrupted block. The list does not describe what each does, so the names are the only official information, but several hint at their role.

5 Build targets

Healing FactorHealth regen of at least 10 per second
Tanked UpA boost that lasts 5 seconds

The four DPS achievements each need a run committed to one damage type, which pairs naturally with the matching Flux Converter. Complete Collection asks you to unlock every block and view the finished Blockpedia.

6 Survive mode scores

The store describes Survive as an endless onslaught of Legion bots and bosses with no checkpoints, no campaign and no way out: just your build and your high score. Four achievements mark score milestones.

Survive has no checkpoints, so defensive benchmarks matter more here than on planets. A Tech that already meets the health and regen targets above is a good starting point.

7 Long counters

Legion bots destroyed
  • 100,000 Legion's Sinking Feelin'
  • 250,000 A Statistic
  • 500,000 A Good Start
  • 1,000,000 Million Dead
Bosses destroyed
  • 20 Who's the Boss?
  • 40 Boss A Nova
  • 60 Boss Rush

These accumulate across every mode, so they arrive while you work on everything else. Survive runs are the fastest way to push the bot count if one lags behind.

Summary

TerraTech Legion has 53 achievements. Clear Dustbowl, Rotwater Basin, Icebound Hollow and Magma Hellscape on three difficulty levels, collect all 48 stars by reading objectives before choosing a driver, and fully upgrade all four skill trees. Attach each of ten corrupted blocks, hit 1,000 DPS with each damage type plus health, regen and boost targets, and push Survive to one million points. Bot and boss counters, up to a million bots and 60 bosses, arrive along the way.
