Checkmate

Checkmate is a 1999 fighting game for the Nintendo 64 game system. The game features 12 playable characters from various video games released prior to 1999. The game is a parody of the Super Smash Bros. series' debut installment for the same console, and was made for the first Lapis Weekly Challenge.

The game is named after a checkerboard, which the game takes hints from for the aesthetics of the main menus. This is due to a checkerboard having 64 squares, and fits with the "64" theme of the console.
