Pepsiman

Pepsiman is a truly bizarre advergame for PlayStation, released in 1999, featuring the eponymous character -- a superhero-ish Pepsi mascot, played by a guy in a zentai suit -- running into or out of the screen depending on the level. The goal is to avoid various obstacles to solve various Pepsi-related problems, such as refilling a vending machine or giving people who are dehydrated a Pepsi.

It also features 3D models made by future Zero Escape writer Kotaro Uchikoshi, apparently.

Allan streamed the game on February 1, 2021, and the stream has been archived on YouTube.
