HiveQueen (2008)

"This is a chess-related abstract strategy game with an insect theme, played on a hex board of 61 cells. Pieces are the Queen, Highborn, Drone, Nurse, Worker, and Soldier. Each type of piece has a unique ability and movement. Soldiers are the only pieces that can capture, but they may only move over friendly pieces to do so. Nurses can "birth" new pieces, if there are enough workers available to support those pieces. The queen is the royal piece, and there can only be one per hive, but a highborn can promote to a queen, with the help of a drone, preventing defeat. Drones are also the only pieces with totally free movement, being able to fly to any open cell, but are limited to 2 per game. The game is won when your opponent does not have a queen on the board at the end of the opponent's movement/promotion phase. "
