MechWarrior 4 'Mech Paks.

The MechWarrior® 4 'Mech Paks will expand the gameplay for the best-selling, award-winning MechWarrior 4: Vengeance, based on the popular game of mechanized combat from FASA Studios™. Each Pak will give players new 'Mechs, a new electronics package, a new weapon, and a multiplayer map. Cyberlore, the team behind the successful MechWarrior 4: Black Knight expansion, is developing the Paks in conjunction with the FASA MechWarrior 4 team.
