Grandpa High on Retro

You play as Grandpa, whose peaceful smoke is interrupted by a phone call that sets him and his grandson on a mission to rescue his mistress. The story unfolds through a deliberately outlandish action-adventure campaign.

Fight through enemy-filled levels using third-person shooting and close-range attacks. You can also move with rolls and slides, and some sequences briefly involve vehicles.

Progress through semi-open but largely linear areas, gathering weapons, ammunition, and supplies. An inventory holds your gear, and locked containers can be opened with a lockpicking minigame.

Players who enjoy the game often point to its absurd, raunchy humor, retro look, and comic story scenes, alongside shooting that they find satisfying. Some also enjoy the deliberately goofy voice performances and music. Reviews frequently describe the campaign as short, and opinions differ on the controls, combat, and voice acting; several players criticize looting and weapon balance.
