Warhammer Survivors Rocket Evolution: Whirlwind Battery

If by rocket you mean Whirlwind Battery, the October-demo recipe is Whirlwind Battery + Liquid Green Stuff → Orbital Bombardment. The developer independently confirms the base-to-evolved relationship, while October player reports establish the companion used in that demo. Morvenn Vahl's Paragon Missile Launcher reference belongs to a separate equipment line. Start with the official artillery reveal and the dated recipe report to identify which weapon you mean.

Identify the rocket or missile weapon first

Rocket is a search shorthand, not a verified item name in the supplied research. Whirlwind Battery is the named artillery weapon whose evolution players commonly mean in this context. The answer is therefore conditional on identifying that weapon. It would be misleading to invent a generic Rocket Launcher item and attach a recipe to it.

The other important missile reference is associated with Morvenn Vahl. The designer's PlayStation Blog post describes her separate Heavy Bolter Fidelis line and Paragon Missile Launcher fire. That equipment is not Whirlwind Battery. Similar descriptions of artillery do not make the two base weapons or evolved results interchangeable.

The October Whirlwind Battery recipe

The October player table gives Liquid Green Stuff as the companion for Whirlwind Battery. Other dated replies corroborate the updated pairing. The result is Orbital Bombardment, which the official April announcement names independently. This gives the line both an officially identified outcome and a versioned demo companion.

Keep those evidence types separate when following the guide. The developer post does not publish the entire passive and chest procedure in the inspected text. The community reports do not become a test of the unreleased full game simply because the result name agrees. The supported practical answer is a corroborated October-demo recipe.

Why Tape Measure is the wrong historical shortcut

An older May recipe used Tape Measure with Whirlwind Battery. The later October replies explicitly correct the companion to Liquid Green Stuff. That is a version difference, not a reason to combine both passives into a new requirement. The current page follows the October material summarized in the source pack.

When comparing two guides, check the build date before deciding that one is describing your current attempt. The older opening list in a discussion can remain visible above newer corrections. Read the dated October replies rather than treating the first line of the thread as the final answer. The evolutions table uses the same October companion throughout.

Preparing the weapon and companion

The recurring demo procedure is to hold the matching passive, maximize the base weapon and collect a boss chest. For this line, the base weapon is Whirlwind Battery and the passive is Liquid Green Stuff. A champion's overall level is not the same thing as the weapon's development. Read the actual loadout state before proceeding on the assumption that preparation is complete.

The research does not establish a universal passive-level threshold or a guaranteed chest minute. It also does not establish that any chest opened without the pair will produce the desired result. Those claims are omitted rather than borrowed from another survivors game. The practical checks remain the correct base, correct companion and the reported boss-chest route.

Liquid Green Stuff also belongs to another recipe

The October table uses Liquid Green Stuff with Brazier Staff as well. That pairing produces Master of Runes rather than Orbital Bombardment. Sharing a passive does not make the base weapons the same or merge the two outcomes. The Brazier Staff guide handles the Age of Sigmar staff line separately.

This is useful when a player remembers the companion but not the attack. Check whether the selected equipment is artillery or the named staff before copying the rest of a walkthrough. The selected universe and actual base weapon matter. A passive name alone is not enough to identify which evolution you are attempting.

Orbital Bombardment is the named result

The April official reveal identifies Whirlwind Battery evolving into Orbital Bombardment. That provides the correct result name to look for in equipment discussion. It is stronger evidence than describing an attack only as bigger rockets. Use the named line when comparing a menu, guide or gameplay caption.

The supplied material does not provide verified damage, missile counts or a universal firing rate for the evolved form. It also does not establish a strongest-artillery ranking. The result's identity can be published without filling those numerical gaps. The weapons guide keeps announced attack names separate from a complete launch stat inventory.

The separate Morvenn Vahl line

Vahl's Heavy Bolter Fidelis evolves into Purgator Mirabilis according to the developer-authored PlayStation article. The same description includes Paragon Missile Launcher fire. Those facts establish why missile footage can refer to something other than Whirlwind Battery. They do not supply an interchangeable recipe between the two lines.

The Heavy Bolter comparison also distinguishes ordinary Heavy Bolter from Fidelis. The ordinary weapon is Boltgun's evolved form and has a different reported companion. Do not use the words Heavy Bolter alone to collapse all those attacks into one sequence. Full equipment names make the answer much more precise than matching only a visual effect.

Troubleshooting a missing evolution

First verify that the weapon really is Whirlwind Battery. Then check that the companion is Liquid Green Stuff rather than the older Tape Measure advice. Compare the weapon's development with the prepared state described in the October reports. Finally, distinguish the reported boss chest from any other reward you opened earlier.

These checks do not create a guaranteed next-chest outcome. They simply separate the possible mismatches in the procedure the sources describe. An unlocked item is not necessarily in the current inventory, and a familiar missile effect is not proof of the correct base weapon. Use the objectives guide when the problem is equipment availability rather than the recipe itself.

Keep the demo build attached to the answer

The Steam description establishes weapon-and-power-up evolutions generally. The precise Liquid Green Stuff companion and reported chest sequence here come from October demo accounts. The full game's exact requirements were not tested by this research. This distinction matters when comparing the trial with a later release or an older video.

The release announcement also states that demo progress does not transfer into the full game. Practicing this artillery line can teach the names and sequence without banking a launch unlock. The research was checked November 8, 2026. The supported answer is conditional on Whirlwind Battery and does not invent a generic rocket weapon, exact timer or unannounced Vahl recipe.
