Pantsmo's Pantaloon Adventure

Update 25th February 2025: a huge new Pantsmo update is here! With many new secrets, including guest appearances from many classic Apogee characters, and a ludicrous number of new pants!

In 1992 Apogee Software released the classic DOS platformer Cosmo’s Cosmic Adventure, a fun, incredible, gnarly, and awesome game with beautiful EGA graphics. Butt... there was a problem! Cosmo was butt naked! Ever had to go on an intergalactic adventure across the galaxy and left home without your pants? Then you’ll know exactly how Cosmo feels. And so…

Presenting Pantsmo’s Pantaloon Adventure! A graphical mod for the original shareware episode that gives Cosmo (and many other things!) pants! Now he can traverse the galaxy in style in a nice comfy pair of pants.

About Pantsmo:

A fun mod created by eviltentacle and Julia Minamata. Download it for free below!

I originally made a basic version of Pantsmo for Julia, the developer of The Crimson Diamond, because she loves games that use the EGA colour palette but she thought Cosmo looked a little too similar to the naked creepy green kappa water sprite from Japanese folklore. So I modded in some nice pants for Cosmo to make him less hideous. And well… then we both just kept on adding pants!
