Space Channel 5: Ulala’s Cosmic Attack is a port of the first Space Channel 5 for the Game Boy Advance (GBA). The plot, characters, and gameplay are identical to the original. In the music video game Space Channel 5, players take on the role of Ulala, a reporter working for the titular news channel in a 1960s-styled science fiction future filled with competing news channels. When an alien race called the Morolians begin attacking, Ulala simultaneously reports on the events, fights off the threat, and clashes with rival reporters.

The invasion is revealed to have been staged by Space Channel 5 boss Chief Blank to drive up ratings for the channel. With help from fellow reporters and support from her fans, Ulala defeats Blank. Players control Ulala through four stages; real-time polygonal character models and visual effects move in synch to MPEG movies which form the level backgrounds. All gameplay has Ulala mimicking the movements and vocalisations of her opponents (compared by journalists to the game Simon Says).

Actions are performed in time to music tracks playing in each section of a stage. There are six buttons that match actions on-screen; the directional pad buttons, and two action buttons (A and B on Dreamcast and Game Boy Advance (GBA), Cross and Circle on PlayStation 2) which are presented with the vocalization “chu”.
