Another freeware & classic port from AnotherGuest: Liero is a DOS based game (first released by Finnish programmer Joosa Riekkinen in 1998) between two worms armed with heavy weapons of all kinds battling in underground caves. In Liero, two worms fight each other to death for score (or frags) using a choice of five weapons from a total of 40 in a two-dimensional map. Most of the terrain, except for indestructible rocks, may be dug or destroyed by explosions. In addition to the weaponry, each player has a ninja rope which can be used to move faster through the map. This SDL port is based on Gliptics' Open Liero.
