Um Jammer Lammy is a rhythm music game developed by NanaOn-Sha and released in 1999 for PlayStation, with later availability on PlayStation 3 and PlayStation Portable. Set in the same world as PaRappa the Rapper, the game follows Lammy, a member of the all-girl pop rock band MilkCan, through a series of guitar-based musical stages. Players must hit inputs in time with humorous and catchy original tracks spanning the band's story. Beyond the single-player campaign, the game includes cooperative multiplayer and a range of unlockable content. The soundtrack leans into comedic scenarios while maintaining an upbeat pop rock sensibility, and the visual style reflects the same distinctive flat, cartoon aesthetic associated with the broader PaRappa universe. It stands as a companion piece to PaRappa the Rapper rather than a direct sequel, centering on a new protagonist and a guitar-focused approach to rhythm gameplay.
Where Lammy goes, mosh pits follow. She's the guitar-slinging megastar of an all-chick band called MilkCan. Help Lammy make it to her big gig on time by jamming to rock, heavy metal, punk, pop and other killer riffs. You can even take on another player with an awesome two-player mode.
