content: Get your heatbeat pounding with the newest expansion to the popular MechWarrior 4 Vengeance!With the addition of new Mechs, like the Sunder, Wolfhound, Uller and More, you will be able to trade on the black market for new weapons and mech chassis.I highly recommend this game, as a sysop with the Microsoft Gaming Zone!!! Play it online with up to 15 other people for the ultimate players experience....
