Barunba © 1990 Namco, Limited.
Barunba is a multi-directorional shooter developed by Zap Corp and published by Namco. The evil Dr Dopperu has plans of world domination and his army of robots brings terror and destruction everywhere they go. The antigravity-ship Barunba is sent to stop the massive threat and to restore peace to the region. The globe-shaped fighter comes equipped with a rather unusual weapon system - a rotating ring is mounted around the ship and gives it the peculiar ability to shoot in any direction (the first action button rotates the ring clockwise and the Run button anticlockwise). The Barunba is also equipped with a fair arsenal of lethal weapons that range from a fast-paced and conventional Vulcan gun (V) to a slow piercing laser (L), powerful Napalm Bombs (N) and a round Shield beam (S) that can be charged up and used as a shield. Each weapon can be switched to on the fly by pressing Select, and they can be individually upgraded up to three times (five upgrade slots and three power levels total) - curiously, they apparently lose their power overtime and need to be regularly upgraded. Barunba consists of five large stages (each featuring a mid-way boss as well as a tougher final boss) and is single-player only.
Barunba was released on April 27, 1990 in Japan for 6800 Yen.
