Enter the Gungeon Robot Past run (no commentary)

This was on a completed save file. You must assemble the bullet that can kill the past before you can access the bosses after the Dragun. The reason I junked the chests was because there's a chance to get an ally called Ser Junkan, and Robot gets a 5% damage boost for each piece of junk you collect. Don't know if it's worth it though. 0:00 Chamber 1 5:39 Chamber 2 10:52 Chamber 3 19:58 Chamber 4 30:09 Chamber 5 42:23 Robot's Past
