MechWarrior is the second video game released in the BattleTech game series. MechWarrior was the first video game to offer the player a chance to pilot a BattleMech from the view of a pilot (a MechWarrior). With this game the player has a great deal of freedom when compared to many of the follow-up MechWarrior games, which include choosing missions, buying & selling mechs and parts, hiring lance-mates, and traveling throughout the Inner Sphere. Underneath the major game mechanics, the player had the option of following a role playing style story arc that would unfold over five in-game years.
The game was ported to the Japanese Sharp X68000 and PC-98 home computers in 1992 and 1993 under the name Battletech: Ubawareta Seihai.
