Windjammers 2 is a sports game that retains the core gameplay from the original Windjammers 2 , with additional content and mechanics. The game involves two players throwing a disc at the other side of the stage to score points. In the standard ruleset, a set ends when the timer runs out or either player scores 15 points, and the winner of two sets wins the match. The sequel adds new types of moves, including the ability to jump and throw mid-air shots, as well as drop shots and slap shots.
New stages are included, some of which score points differently to the standard ones, with the Casino stage notably scoring them depending on the number printed on the disc instead of the zone it ends up in.
The game has a roster of 12 playable characters, including a hidden character. Gameplay modes include an arcade mode (a singleplayer campaign with progression and occasional mini-games), local matches against the computer or a second player, online multiplayer, a manual listing of moves, and a practice mode with playable tutorials and AI opponent configuration options.
