Pieces in apocalypse move and capture in the same way as their chess counterparts. Both players declare their move at the same time. At the end of a turn, once both players declare their move, moves from both players are applied at the same time. If both players move pieces to the same square at the same time the following happens:

1. If both pieces are knights, or both pieces are pawns, then the pieces are destroyed.
2. If one piece is a knight and one is a pawn, then the pawn is destroyed and the knight successfully moves.

If a pawn reaches the opposite side of the board it is promoted to a knight. The first player to eliminate ALL the other player's pawns is victorious.
