If you're looking to get from planet to planet or maybe get down to the surface, you'll need a craft to get there. And Catalyst Game Labs is giving you some options with their Alpha Strike card sets for Battletech. They have released ones for WarShips, JumpShips, and DropShips. And they're free to download, too!
From the announcement:
Long-awaited and much-requested, new today in the store are Alpha Strike cards for WarShips, JumpShips, and DropShips and other small craft–completely FREE to download, or pay what you want. Nuke them from orbit, it’s the only way to be sure!
