Plan an Eviscerator or Meltagun run

Eviscerator Chainsword demo artwork

For a focused Warhammer 40,000 run, aim for Eviscerator Chainsword or Meltagun. Each route below shows which weapon and passive to collect.

  1. Choose Malum Caedo, who starts with Chainsword.
  2. If Tape Measure is still locked, survive one minute in Warhammer 40,000 to unlock it.
  3. Pick up Tape Measure during the run and keep it alongside Chainsword.
  4. Level Chainsword toward its eighth and last level, where the evolution is listed, and open chests.

Eviscerator Chainsword is a brutal horizontal slash that inflicts Bleeding. The Tape Measure level and exact chest conditions it needs are not known.

Pair Lasgun with Gauntlet. Gauntlet is unlocked by default, so no separate unlock goal is needed, but you still have to pick it up during a run.

Kozlowski starts with Lasgun, which makes him the simplest route to this pair once you have rescued him on Imperial Bastion. A separate goal, reaching rank 6 with Lasgun, adds Lasgun to the general weapon pool.

Lasgun fires at the nearest enemy and loses damage over distance. Meltagun is a powerful short-range beam that deals bonus damage to bosses and close enemies. Both benefit from being closer to the target, so leave room to dodge.

Try these steps:

  • Make sure you have the correct base weapon and passive, not a similarly named item.
  • Try levelling the base weapon to its eighth and last level, where the evolution is listed.
  • Try levelling the passive and opening another chest. Its required level and the exact chest conditions are unknown, so this may not immediately give you the evolution.

The 500-coin achievement for obtaining Meltagun requires the Kozlowski rescue first. That prerequisite applies to the coin reward; the Meltagun recipe itself only lists Lasgun and Gauntlet.

Keep the evolution pairs and unlock goals open beside this route.
