ULTRACRAFT is a mod based on ULTRAKILL and its many features.
Same as its in game version, left click shoots and right click shoots an explosive round.

Also same as its in game version, left click shoots and right click is a piercing shot
This mod also adds a new biome, the flesh biome, this is where most of the content from the mod is.
Included in this biome is the new structure, an arena made with pillars of bone and a boss spawn in the middle, spawning Gabriel, along with chests along each side.

Skin: Planet Minecraft
Here he is, Gabriel, mostly simalar to his ingame appearance, however some attacks are different. Other then that it is just Gabriel.
Thats pretty much it for the mod, however I do plan to expand upon this in the future, and possibly make even more content.
