I’d never played this until tonight when I found it lurking inside my MAME cabinet. Turns out it came out in 1994 as part of Taito’s F3 cartridge system, similar to Neo-Geo but not as popular. I always liked the original game but found it kind of frustrating. The sequel (’cause it’s also known as Elevator Action II, apparently) feels more forgiving, has a lot more detail, more interesting environments and – I hate to say it – felt more fun.
This is why I love having a MAME cab. Full of surprises.
