Have you ever been bored on a flightpath? How about waiting for that bunker to cap in AV? Perhaps you've sat there in front of Black Temple waiting for the other 24 members of your raid and said to yourself, "Man, I wish I had something to do other than /dance with Archmage Vargoth for the 100th time."
Flightpath Puzzle League is a mod which adds a fully-featured implementation of a Tetris Attack-style puzzle game to your in-game UI, including tutorial animations that explain the basics of the game, flightpath and friends list integration, and full multiplayer support.
Visit the mod page for videos of the multiplayer and singleplayer game modes:
