Axe from Dota 2 joins Baldi's school as your ally
Play Baldi's Basics Classic Remastered with Dota 2's Axe as a real school ally.
Axe's portrait, animated model, and Berserker's Call sound are read from your own Dota 2 install. He follows you through the school and automatically casts Berserker's Call to pause Baldi for a few seconds when he gets close.
You need both games: Baldi's Basics Classic Remastered (the game you play) and Dota 2 (required companion). Solo only.
Nothing from either game is in the download — every player uses their own copies.
