Set in the Battletech universe, this collectible card game deals with big mechs; the goal is to hit opponent's bases and therefore "scrapping" his card (discarding cards from the deck). Once a player's deck runs out of cards, he loses.
There were several expansion sets including: Mechwarrior, Counterstrike, Mercenaries, Arsenal, Commanders & Crusade. Below is a link to a file that documents the entire card set.
