In between stages, the player is shown videos of an American man (played by Mike Butters) drinking Pepsi and eating chips and pizza as he watches Pepsiman. Each stage ends with Pepsiman being chased by an object, such as a giant Pepsi can. Throughout each stage is a number of checkpoints if Pepsiman gets hit by obstacles too many times, the player is required to restart from the latest checkpoint. In some stages, Pepsiman's head becomes stuck inside a steel drum, which inverts the controls, and in some, he rides on a skateboard, which requires to player to avoid all obstacles. The player gains points by collecting Pepsi cans. The player does this by using four different moves: running, dashing, jumping, and super-jumping. The player takes control of Pepsiman himself, aiming to dodge obstacles, such as cars, construction cranes, and people, as well as Pepsi-branded obstacles, including a Pepsi truck. The game is played from a third-person perspective, with Pepsiman automatically running forward through the stages, sometimes running through homes and other buildings. The first three stages are based on real locations, San Francisco, New York City and Texas. Pepsiman is an action game that consists of four stages, each divided into smaller segments, and each involving the superhero Pepsiman saving a person who is dehydrated, such as a military man in the middle of a desert, by giving him a can of Pepsi. Here, he is jumping on an intersection in an attempt to avoid a moving car. According to Uchikoshi, the game did not sell well. A writer for Complex included it on a list of company-branded games that 'didn't suck', commenting that it is not a bad game as long as the player can tolerate the large amount of advertisement in it. Reviewers frequently compared Pepsiman to other games, including Crash Bandicoot, and commented on its simplicity and its price, which was thought to be low. While an American publisher did look into acquiring the rights to publish the game in the United States, it remained a Japan-exclusive game.

The game also features 3D cutscenes, for which the future visual novel writer Kotaro Uchikoshi created 3D models. The game was made on a low budget, prompting the decision to make videos in-between stages that show a man drinking Pepsi, as they were cheap to produce. It focuses the player on avoiding obstacles by running, dashing, and jumping, while Pepsiman automatically runs forward through each of the game's stages. It was released in Japan on March 4, 1999, and is based on the eponymous Japanese superhero mascot for the American carbonated soft drink Pepsi. Pepsiman is an action video game developed and published by KID for the PlayStation.
