Wehrmacht is a diceless science fiction miniatures wargame depicting combat between giant, piloted, robotic warmachines called Knights. Each player controls a cadre of Knights that fights for a Royal House in a far future Feudalocracy. The game is played on a tabletop using miniatures for the Knights and representative scenery. Knights perform actions using an alternating sequence. When activated, a Knight may move (via measurement in inches on the tabletop) and perform an attack action. The combat system is diceless and invovles comparing an attacker's Fire Control System (FCS) or Melee Control System (MCS) rating to the target's Evasion Control Systems (ECS) rating. If the ECS is exceeded, an attack hits and does damage. At the beginning of each turn, players secretly select a Combat Mode for each Knight that determines its basic FCS, MCS, and ECS ratings for the turn. These ratings may be modified by various upgrades and other actions that may be taken during the game.
