Flotilla

Turn-based naval strategy game inspired by Battleship and XCOM and written in Godot

Basic gameplay is similar to Battleship, with some exceptions:

• Rather than a 10x10 rectangular grid, each player places their ships on a 15x15 hexagonal grid. Ships can be placed diagonally.
• Rather than starting with one of each ship, each player is alloted a certain amount of points to purchase ships, and can choose their own fleet composition.
• Some tiles are island tiles where ships are not allowed to go. Coastal batteries can be placed on these tiles.
• Every ship is allowed to fire at least once per turn.
• Every ship is allowed to move at least one tile or rotate at least 60° per turn, unless more than 50% damaged.
• Most ships have a special ability that can be used after a cooldown period.
• Most ships have a passive ability that improves their effectiveness.
• Some ships have a second special ability to really mix things up.
• Some ships have drawbacks that reduce their effectiveness under specific conditions.
