The official MechWarrior 4 site has unveiled a new page for Black Knight, announcing an expansion pack for the stomping 3D action/sim by the FASA Interactive team and Microsoft. The pack is being developed in collaboration with Cyberlore (creators of Majesty) and "takes you back into action on Kentares IV with new 'Mechs and vehicles, more ways to modify your 'Mechs, several new multiplayer modes, and a new single-player campaign where you can play a Black Legion mercenary fighting for House Steiner." Three new screenshots offer the first glimpse of the expansion, which is scheduled for a Fall release.
