BattleTech: Missions is a cooperative campaign using the Core Rules and Total Warfare ruleset for infantry and vehicles.

Each player plays the role of a Mech pilot working for a small mercenary company. Players will develop their pilots over the course of a series of missions. At the end of each mission, pilots are assigned C-Bills and XP with which they can upgrade their Mech and Pilot for subsequent missions. The missions can be played in any order. Generate your own pilot or use one of the progenerated pilots provided.

3027-3: Aberystwyth -Okay Boys, listen up! Henrik is sifting through the intel contained in the navigational logs of the pirate dropship you worked over. It sounds like he's close to figuring out where to find their base so we can be done with this mess, and move on to more exciting things. In the meantime, the local authorities have tracked down the last of the pirates on the ground, and I’d hate for you to get bored twiddling your thumbs while you wait for that nav data. Before we pack up to who knows where, head out to grid point kappa, and see if you can capture or kill the pirate leader, and finish off the pirate threat on Aberystwyth before we go. Just remember: Those pirates are cut off, cornered, and have had at least a few hours to dig in, so be prepared for anything! Oh yeah. It turns out the local government is offering a bounty for each additional pirate you can get rid of. Big money's on the boss, but what they're payin' for other pirate scalps should pay for at least a couple of rounds of drinks. Have fun out there
