Just found a cool trick in SBTF.
If you go into the snapshack before extended play mode you will somhow get:
and this was AFTER I got the army shirt and camo pants, so im assuming that this glitch unlocks all clothes apart from the max + crossbones shirt.
Im not sure if this helped, but I had a 100% save file of Homestar Ruiner.
Also, this happend to me twice! Both in a different playthrough.
What do you think of this? Glitch? Easter Egg? Time Travel? post what you think below!
