Contamination

by SakePlayS

Contamination turns the world into a contaminated wasteland across three stages, and players must craft a Hazmat Suit and a Particle Suppressor to survive it.

What it does

Welcome Contamination, previously known as Irradiation, changes the world into a contaminated wasteland that players try to survive. Vegetation begins to decay under the influence of the contamination, and the world's air eventually fills with a deafening silence. Contaminated mobs spawn and grow stronger in later stages, and elite contaminated mobs gain the ability to spawn spreaders.

The progression is split into three world contamination stages. Stage II makes contaminated mobs stronger and vegetation decays faster, while Stage III makes vegetation decay fast and lets spreaders appear. Any creature within the safe zone that is not wearing a Hazmat Suit dies, so the suit is the basic requirement for staying alive.

The mod needs Curios API and Geckolib as required dependencies. The server and every player need the mod installed. Files are published for NeoForge 1.21.1 only, and the mod is released under the MIT License but is not open source.

Key features

  1. Hazmat Suit

    The Hazmat Suit is given at the start of a world charged with RE resonant energy-rich items, and its charge must stay above 0 to walk freely among contaminated particles.

  2. Particle Suppressor

    The Particle Suppressor lets normal mobs spawn and lets players survive within its radius for as long as it stays powered by RE.

  3. Suit Workstation

    The Suit Workstation charges the suit and upgrades the Particle Suppressor, increasing its radius, efficiency and fuel capacity.

  4. Suit upgrades

    Suit upgrades raise the suit's contamination resistance and charge capacity, and the Suit Workstation applies them.

Questions

Does Contamination need Curios API and Geckolib?

Yes. Both Curios API and Geckolib are required dependencies, so both must be installed alongside Contamination.

Does Contamination have to be installed on both sides?

Yes. Installation covers the server and each player's game.

What happens if the RE-rich items run out?

The author notes that running out of cost can leave a world stuck in an infinite death loop that can only be broken by entering creative mode, so players should stock up on RE-rich items.
