So I stumbled upon a one glitch in killhouse that allows you to have 2 crossbows at once. First of all, create an alt. account and join saktk then killhouse. Collect all stuff for a Speedrun (also you supposed to take crossbow). Then, beat the killhouse in less than 45 seconds, and the glitch is done. Because you got a badge and you given a crossbow, but you already have one, so the game will give you the 2nd crossbow.

P.S: I'm not English so I'm sorry for all grammar mistakes.

I know everyone found out this like 72396 decades ago so I don't really know why do I write this.
