This is a mod for Risk of Rain 2, known as 'Starting Items' and was created by Phedg1Studios. The mod allows the player to start off with whatever items they want. The only real restriction is that you can only choose items you have found/discovered while playing the game.
Pretty basic and self-explanatory really - although I definitely recommend checking it out, it can be really fun for blasting through levels or experimenting with items / play-styles you rarely get to try out thanks to RNG.
This mod requires BepInEx and R2API to run correctly.
