Nuclear apocalypse

The mod is inspired by the oldest challenge in Minecraft and adds realism to it. As soon as a player enters a new world, a countdown begins. A skiptimer command fast-forwards the timer to the last 30 seconds, and when it reaches zero, an explosion sends an enormous shockwave across the land and burns everything in its path. The blast also leaves lots of radiation in the world.

Below Y 30, the radiation reaches the player. Walking unprotected for too long causes radiation poisoning, which grows progressively worse and must be cured with a golden apple before its effect ends, or the player dies. Metal armor protects against radiation for five minutes, then breaks after becoming saturated. There are four types of protective armor, and the metal armor can be upgraded with iron, diamond or netherite to raise its protection level. Metal ore is found between Y 30 and Y -64.

Nuclear apocalypse runs on client and server, so the server and every player need it. Installation needs Forge, and files are published for 1.21 and 1.21.1, with 1.21-1.21.1 as the latest file for 1.21.1. The code is under the MIT License and is not open source.
