If you are wondering how to get Nuclear Star in A Universal Time, this step-by-step guide covers the entire AUT 5.0 route from Lab access and space materials to Catalyst crafting, the boss encounter, and the final transformation using Made in Heaven.
What is Nuclear Star in AUT 5.0?
Nuclear Star is a new stand in AUT 5.0 with distinctive moves, voice prompts, and a special cutscene. Unlike simple arrow rolls, the unlock path threads through the revamped Lab system, a multi-biome space dimension, and a one-shot boss fight. You will collect Camelites and Cosmic Fragments, craft a single-use Catalyst, win the encounter to earn a Nuclear Core, then apply that core to Made in Heaven to complete the transformation. The result is a sought-after stand with strong potential in both PvE and PvP.
This AUT 5.0 Nuclear Star guide focuses only on the confirmed game flow so you can plan your farming and crafting with minimal backtracking.
How to Get Nuclear Star in A Universal Time
1) Unlock the Lab in the desert
Farm Camelite Fragments from meteorites until you obtain a key card, then use it to enter the Lab. Speak with the Cafeteria NPC to start the questline. This opens access to Lab progression and the systems you need for materials and recipes.
2) Learn the three Lab sectors and build Reputation
Green (Analytics): trade materials for Reputation, unlock recipes, and pick up quests.
Yellow (Refinery): craft items from unlocked recipes.
Red (Gateway): access the Wormhole to space.
Upgrade your key card with Reputation gained by exchanging rare items (Camelite Fragments, Cosmic Remnants, Crystalline Cores) or returning equipment crates to the Storage NPC.
3) Craft the Mining Laser
Unlock the Mining Laser recipe in Analytics, then craft it in the Refinery using Camelite Fragments + Metal Scraps. The laser is your ticket to efficient space gathering and is required for the key materials.
4) Gather materials in the space dimension
Enter space via the Gateway’s Wormhole. The dimension has three biomes:
Biome 1: harvest orbs.
Biome 2: the priority zone for Nuclear Star; mine crystals for Camelites and battle golems to obtain Cosmic Fragments.
Biome 3: delta farming.
Monitor radiation and leave before it hits 100% to avoid setbacks. For how to farm Camelite Fragments AUT, continue meteorite salvage in the desert, then shift to Biome 2 for Camelites via mining.
5) Craft the Catalyst (AUT Catalyst crafting guide)
In Analytics, unlock Advanced Materials. In the Refinery, craft Catalyst = 2 Refined Camelites + 2 Cosmic Fragments. Consider preparing more resources than the bare minimum because the Catalyst is consumed on use.
6) Trigger the boss fight on the Wormhole bridge
Use the Catalyst at the bridge to start a duel against your past self. All traits and levels are disabled, and you have one attempt. If you fail, the Catalyst is lost and you must re-farm materials and craft it again.
7) Claim the Nuclear Core and transform
On victory, you receive the Nuclear Core. Apply it to Made in Heaven to complete the Made in Heaven to Nuclear Star conversion. This final step unlocks the stand with its unique moveset and presentation.
Practical tips
Farm extra Camelite Fragments early to smooth later crafts and key card upgrades.
Upgrade the key card steadily through Reputation turn-ins and crate returns.
Rush the Mining Laser to accelerate Camelites and Cosmic Fragment collection in Biome 2.
Treat the boss as a no-mistake check: prep mechanically, since traits and levels do not help.
Use the Catalyst carefully; a failed attempt means repeating the craft.
Final Thoughts
The clearest path for how to get Nuclear Star in A Universal Time is linear: unlock the Lab, build Reputation, craft a Mining Laser, farm Camelites and Cosmic Fragments in Biome 2, craft the Catalyst, defeat your past self, then use the Nuclear Core on Made in Heaven. Follow the steps above to minimize wasted runs and secure the stand efficiently for both PvE and PvP play.
