You are the genetically engineered Clan Mechwarrior. MechWarrior II is set in a world where the Clans are invading the Inner Sphere. You can join either the Wolf Clan or the Jade Falcon Clan as they pursue their own agenda against the Inner Sphere and other Clans. Take your advanced Omnimechs into battle against all comers. Win high warrior ratings (by using less mechs or smaller mechs than needed, completing secondary objectives, etc.) and you'll get a chance at a promotion trial where you face superior odds in an arena. If you win, you advance in rank. If you are very successful, you can make it all the way up to Khan, leader of the Clan.
