Crimson Islands

Crimson Islands is a rare biome in Pixelshift that spawns in the Ocean. By the meaning of crimson, the entire biome (except for the Dungeon structure) is red, including the sky. This is also the ONLY biome where Nak can be summoned. If the player exits the Crimson Islands or goes up to Space while fighting Nak, they will die instantly and will have to hike back to try again.

Dungeon
The Dungeon is a VERY rare structure that can be found in this biome. It is entered by jumping into the Purple Bricks and then typing 'Y' in the command prompt.
