Liero is a video game for MS-DOS, first released by Finnish programmer Joosa Riekkinen in 1998. The game has been described as a real-time version of Worms (a turn-based artillery game). Liero is Finnish for 'earthworm' and is pronounced [ˈlie̯ro]. Inspired itself by the earlier game MoleZ, Liero provided inspiration for the later games Soldat and Noita.
