Assimilation Chess combines elements of Fusion Chess and Chessgi. Unlike Fusion Chessgi, which is a straightforward hybrid of these two games, Assimilation Chess slightly changes the rules of Fusion Chess to create a game in which you can add to your own material by capturing enemy pieces. Instead of holding onto a captured piece for future deployment, you assimilate the captured piece into the capturing piece whenever the two pieces are non-identical simple pieces. For example, a Knight that captures a Rook becomes a Marshall, or a Rook that captures a Bishop becomes a Queen. When a simple piece captures a Pawn or a compound piece, or when a Pawn or compound piece captures anything, the capture does not change the capturing piece.
 
The game's name is inspired by the Borg from Star Trek, who regularly increase their numbers by assimilating their enemies.
The object is the same as it is for Fusion Chess, to checkmate your opponent's current royal piece.
 
The board was made from computer generated textures.
