Mod Installation: Crack-Life Anniversary V11 Steam Thread

Ive Looked up Guides On how to install it but the Best I could do was Get the In-games (Change Game) Option to appear but the game doesent. Ive read up on some of the Earlier Guides for previous versions about a "Steam Pipe" Engine That was used to get Mods like this running But I dont know if its needed anymore or if I need an Engine provided from this site to work it
