UltraEditor is a lightweight mod for ULTRAKILL that adds an in-game level editor, letting users create complete new levels and explore community made ones.
Just press "Create level" in the chapter selection screen to go to the editor! Then, press F1 to toggle the editor on and off.
Of course! Inside the editor, press "Help" and then click on any of the avaliable tutorials, with more coming soon! There's also a planned documentation to come out at some point with the mod to let everyone made anything easily!
Just press "Explore levels" in the chapter selection and a list of levels should appear! If that's not enough, join our discord and see what others make! You are also able to share levels there, so if you make anything you are proud of, share it!
Join our discord and any of your questions should be answered!
