Rocket Evolution

Quick Answer

Combine Storm Eagle Rocket with White Dwarf to obtain Deathstrike Missile. Unlock the rocket by surviving 20 minutes in one run, then max the weapon and open a boss-dropped chest with the passive equipped.

The rocket evolution is Storm Eagle Rocket + White Dwarf = Deathstrike Missile. White Dwarf is the passive you need for this recipe.

Unlock the two ingredients

IngredientUnlock requirement
Storm Eagle RocketSurvive 20 minutes in a single run with any character.
White DwarfReach character level 10.

These are unlock objectives, not the final evolution trigger. Surviving for 20 minutes puts the rocket into your available pool; it does not automatically award Deathstrike Missile.

Recognize Storm Eagle Rocket

Check the full weapon name before committing your passive slot. Storm Eagle Rocket is the base weapon for Deathstrike Missile. Whirlwind Battery belongs to a separate evolution route and is not an interchangeable rocket ingredient.

Complete the evolution

  1. Obtain Storm Eagle Rocket in your run.
  2. Add White Dwarf to your passive items.
  3. Upgrade Storm Eagle Rocket until the base weapon is maxed.
  4. Open a boss-dropped chest with both ingredients equipped.
  5. Confirm that the resulting weapon is Deathstrike Missile.

Use the rocket's maximum upgrade state to judge readiness. Your character level and White Dwarf's unlock milestone measure different things.

Fix a missing evolution

Start with the two easily confused conditions: unlocking an item and equipping it are different, and reaching character level 10 is only White Dwarf's unlock requirement. Neither proves that White Dwarf is in your current loadout.

If both ingredients are present, check whether Storm Eagle Rocket still has upgrades remaining. Then pursue a boss chest instead of expecting the transformation to happen as soon as you collect the passive. Keep this route separate from Orbital Bombardment, which evolves from Whirlwind Battery.
