The Inner Sphere is launching a counterattack on the Clans, and the Smoke Jaguars is the first target! Operation Democles will attack the planet Tranquil. As Connor Sinclair, you're leading the Democles Commando team lance, part of the Eridani Light Horse, on the attack. The op went terribly wrong when one of the two drop ships was hit during descent, and your lancemates have been scattered to the four winds in the frenzied drop. You must attack through Clan territory, meet up with your lancemates, remove any resistance in your path, and try to find a way off the planet, while also accomplishing what you came to do: destroy the Smoke Jaguars!

MechWarrior 3 features detailed mechs (they limp when legs are hit, and destroyed limbs spark and trail wreckage) with slow and ponderous movements, as 100 ton mechs should. Firepower and precise application are the key in winning your engagements. Plenty of mechs are available. You start in a 55-ton Bushwhacker and work you way up to the really heavy stuff in a 20-mission campaign. Full multiplayer is supported with Internet play at Microsoft Zone. Your MFB has limited capacity so you'll need to decide what supplies to keep or dump for your salvage. You'll need to track ammo, weapons, equipment (like heatsinks), and the mechs. Keep the MFB safe or you'll have even less room! Redesign mechs to utilize newly captured weapons or adapt to the changing ammo situation.
