UPDATE: This game was featured on the front page of www.minecraftforum.net on 12/26/13! Thank you all for checking it out, supporting it, and sharing it!

My take on the Battleship board game. The game supports two players (and any number of observers). The project took roughly a month to create. Download and play it today!

Features:
-Full preview board for deployment
-Random selection to determine who attacks first
-Spawnable vertical and horizontal ships
-Fully destructible ships
-Win detection
-Observer team allowing creative gamemode

Feel free to add this to your server and/or make videos of you playing through it - just please leave the command block and signs crediting myself as the builder in there. And if you do make a video of playing the game, share it with me! I'd love to see it!

Additional Notes

This map uses large numbers of setblock and summon command blocks, and will therefore only work on Minecraft 1.7+.
