Crimson Marker Plague

Quickstart

• Start a survival world and look for the crash site: the Crimson Prime Alien Marker arrives on day one, and the surrounding infection can spread.
• To make a Marker yourself, craft one with crimson fungus, Nether wart, sculk, a sculk catalyst, and bones:

• Prepare before exploring infected ground. A Sealed Gas Mask uses a Gas Filter Cartridge; keep filters and a Biomass Cure with you. The cure recipe uses a Contained Biomass Sample, honey, a golden carrot, a glass bottle, and a filter:

• For ranged defense, craft the AK-74U or Plague Response Shotgun, then bring the matching ammunition. Reload with the Reload AK-74U / Shotgun keybind; check Options → Controls for its current binding.

Overview

The Marker’s arrival brings crimson biomass, spores, infected terrain, and creatures that can join the hunt. Explore carefully, gather materials from the crash and contaminated areas, and prepare for encounters with both plague creatures and Necromorphs.

What It Adds

• Marker and infection: the Crimson Prime Alien Marker, Crimson Biomass, Crimson Spore Mat, Crimson Hive Heart, and other infected growths.
• Infected terrain: Crimson-Infected Wood and Leaves, Crimson Spore Blooms, Biomass Tendrils, Infected Tree Eggs, Crimson Fungal Matrix, Infected Bone Mass, and Biowaste Cysts.
• Creatures: Crimson Crusher, Infector, Flyer, Hunter, and Waster, along with an Infected Player Echo. Necromorphs include the Boneblade Slasher, Infector, Severed Hand Crawler, and Crying Necromorph Baby.
• Survival gear and weapons: Crimson RIG armor, a Sealed Gas Mask and filters, an AK-74U, a Plague Response Shotgun, and their ammunition.
• Places and salvage: an Abandoned Bioweapons Lab, crash-site materials, and a Gunsmith Table.

How To Use

• Explore the outbreak carefully. Watch for biomass, spore growth, infected plants, and hostile creatures. Infected mobs can become part of the hunt.
• Treat infection as a survival threat. Keep a Biomass Cure ready, and wear a Sealed Gas Mask when heading into spore-heavy areas. Gas Filter Cartridges are also used to make the mask and cure.
• Fight at range when possible. Carry ammunition for your weapon and reload with the configured reload keybind.
• Try the Necromorph skill tree. Use the Open Necromorph Skill Tree keybind; its binding is listed under Options → Controls.
• In Creative mode, use the mod’s spawn eggs to place its creatures.

Crafting And Obtaining

Recipes are available in the recipe book. Many of the mod’s materials are found among the Marker’s growth, crash wreckage, and bioweapons-lab salvage.

Abilities And Mechanics

• Biomass infection: the outbreak affects creatures and spreads across the environment. The infection has a named Biomass Infected Stage 1 effect.
• Plague and Necromorph threats: expect several enemy types rather than a single creature. Necromorphs also have effects named Bleeding, Rending, and Necromorph Form.
• Infected growth and salvage: contaminated blocks include biomass, spore mats, tendrils, infected wood and leaves, and other growths. Crash salvage includes Wreckage Steel and Crash-Site Alloy.

Progression And Strategy

1. Secure food and basic supplies, then locate the crash area and note where infected terrain begins.
2. Gather salvage and craft a ranged weapon with ammunition. Keep track of reloads during encounters.
3. Make a Gas Filter Cartridge and Sealed Gas Mask before venturing into spore-heavy areas; save a Biomass Cure for infection.
4. Explore the infected growth and the Abandoned Bioweapons Lab for additional materials, then improve your protection with Crimson RIG armor and Bioseal Alloy.
