Flotilla is a three-dimensional simultaneous turn-based strategy space combat video game set in a randomly generated galaxy. The player and computer-controlled opponents issue orders to their ships, which are carried in a simultaneous and real-time fashion over a period of 30 seconds. The game then freezes, and the player and opponents issue new orders to their ships, which are again performed for 30 seconds. This process repeats until one party is defeated.Orders are separated into three groups: attack move, flank move and focus fire. An attack move orders the ships to move and fire simultaneously; a flank move increases the ship's speed but deactivates weapons until the ship stops moving; and focus fire increases fire rate but significantly reduces the ship's speed.
