|You are Eric McClair, dishonorably discharged from FedSun military
when you went off to rescue a fallen comrade, thus disobeyed a direct
order. The only place that will take you is the Black Knight Legion,
a mercenary group headed by Colonel Lawhorn in his name sake mech,
the Black Knight. This expansion disk for Mechwarrior 4 requires the
original to play. There's an all new single-player campaign where
you will visit Kentares IV. You get to fight and pilot five new mechs
(Black Knight, Sunder, Ryoken, Uller, and Wolfhound). You get some
new weapons as well, like X-Pulse lasers, large autocannons, and more.
There are also new multiplayer modes. The best feature, however, is
"black market" in the single-player campaign. You can use the black
market to trade in mechs and weapons you don't want for other mechs
and weapons that you do want.
