Warhammer Survivors Whirlwind Battery: Orbital Bombardment

Whirlwind Battery evolves into Orbital Bombardment with Liquid Green Stuff. The release table lists the base weapon at level 8; the original October demo post records the same named companion.

Build around the right item

Liquid Green Stuff is the companion name in this chain. Do not silently replace it with Glue because both sound like hobby supplies. The passive-item lookup shows which named companions serve different weapons. A similar theme or icon is not enough to establish interchangeability.

Raise the weapon's own level and carry the companion before opening an eligible chest. The official April reveal already names Orbital Bombardment as the evolved weapon and describes attacks from above, so the result is not inferred solely from the game's name.

What this tells you about positioning

An attack arriving from above gives a different visual and tactical pattern from Malum's horizontal Chainsword. Keep your movement decisions tied to the hazards you can see rather than assuming a bombardment covers every safe route. This is editorial planning advice; no measured area, firing interval or best damage ranking is supplied by the sources reviewed here.

When the chest gives something else

Check that Liquid Green Stuff is actually held, that Whirlwind Battery is level 8, and that the reward was not a normal weapon upgrade. The release reference describes chest eligibility by stage and reward slot. It does not support a universal minute at which every chest must produce this result.
