What it does

Blocks and items from the original mod are carried over to Forge 1.20.1. The explosive content includes nuclear bombs and landmine charges, and the radiation contamination system spreads hazards across chunks, which a Geiger counter can detect. A bomb caller can summon aircraft for flyby strikes, and missile systems round out the military content. Each item and block is marked in game as Working, WIP or Implemented, so players can see which parts are finished.

The port is meant to be used with worlds created on the original mod, though it is not a complete match for them. Because many survival-related systems are still incomplete, the author recommends Creative Mode. The mod is client and server, so the server and every player need it, and it requires additional mods to be installed alongside it. Files are published only for Forge 1.20.1, and the latest is 1.0.33-1.20.1-port-alpha, released 2026-09-14 on the alpha channel.
