Description
An addon for Alex's Caves that changes how you obtain and craft nuclear bombs, as well as improving the effects of nukes on the environment.
> **WARNING:** It is recommended to **turn OFF item drops from the nuke** in Alex's Caves configs! Also setting the nuke radius in Alex's Caves to `6` or higher is recommended—the explosions have been optimized for larger radii.
**Dependencies:** Citadel, Patchouli, Cloth Config, Kotlin For Forge, and [Alex's Caves](https://modrinth.com/mod/alexs-caves) (of course)
---
To get started, craft a guidebook using a book and `alexscaves:uranium` (Requires Patchouli). There is also `EMI` support for the new recipes and in-world block transmutations.
**This mod adds:**
Spoiler
- Enriched uranium, rod, block
- Overhauled nuclear explosion
- Uranium enrichment process
- Rocket launcher and rocket types
- Uranium arrow
- Uranium candy
- New types of nukes (Mini-nuke, Neutron bomb, Black hole bomb)
- Nuka Cola
- Raygun MkII (And gamma variant)
- Flamethrower
- Railgun
How to enrich uranium:
Spoiler
Smelt uranium blocks in an Alex's Caves nuclear furnace to get a *Block of Salted Uranium*. Then put that block in a *Centrifuge* and wait (will take a while).
Smelting uranium will leak radiation in the surrounding area so get your hazmat suit on to make sure the nuclear furnace doesnt overheat!

Server side performance settings:
Spoiler
Note explosions have been optimized compared to Alex's Caves. For weaker hardware, you can try the following settings, in order of greatest to least impact:
- Turn off "Create glowing irradiated air" in nuclear explosion config (glowing air may cause light updates and significantly increased memory usage)
- Reduce explosion radii for neutron bomb, black hole bomb, mini-nuke (nuke follows Alex's Caves)
- Set effect cloud duration to 0 in nuclear explosion config
You may use this in modpacks!
