Imperial Bastion rescues and rewards

Steam hotfix 2.1.6Updated

On this page

Reach character level 20 on Imperial Bastion to open Gallowdark. This is a level objective in one run, not a requirement to defeat the stage’s final boss before the second map can appear.

Separate the stage’s objectives

Goal Condition
Open Gallowdark Reach level 20 on Imperial Bastion
Add Trooper Kozlowski Find and rescue him on the stage
Add the Legend of Catachan Find and rescue him separately
Collect Abaddon Black Obtain the stage’s paint pot

These tasks can be attempted in the same visit, but completing one does not mark the others complete. The rescue guide covers rescue markers and combat, while paint pots explains the later character collections that use Abaddon Black.

Boss-wave reward schedule

Wave minute Evolution-capable slot?
1 Yes
3, 4, 6, 8 No: existing-equipment upgrades
10, 11, 13, 15, 16, 18, 19, 21, 23 Yes

These are scheduled reward rows in the current stage data. A boss spawning at that minute and its chest being collected are different moments. The existence of an evolution-capable slot also does not guarantee a specific result: the recipe and reward selection still have to qualify.

This schedule is why a universal “wait ten minutes before any evolution” rule is incorrect. The minute-one reward has an eligible slot, although an early run may not yet have assembled a maxed weapon and its passive. Conversely, an intermediate chest can remain upgrade-only even if your recipe is ready.

Tyranid pressure

Synapse creatures strengthen nearby lesser Tyranids with Berserk. Killing the Synapse source temporarily stuns nearby lesser bioforms. Prioritize the source when it is sustaining a dangerous group rather than treating every buffed small enemy as an independent threat.

Von Ryan’s Leapers can pounce over other enemies. A lane that appears blocked by ordinary bodies is not proof the Leaper cannot reach you. Enemy auras and telegraphs connects these specific behaviors to movement decisions.

Steam hotfix changes

Version 2.1.6 fixes inaccessible dropped chests on Imperial Bastion and the rescued Catachan champion using the wrong weapon. On the patched Steam version, his signature rescue weapon is Frag Grenade. Other platforms have a separately announced rollout; the hotfix page keeps that distinction visible.
