This is the classic battleship game written in XNA. Unfortunatelly I lost the last version when Megaupload closed, and this one is completed by 70%, but it can be played. In this game I cover a lot of 3D techniques that I have learned over the years. This is a ported version of my first game. The first version was with opengl and c++ builder and it was less complex. here are the download links, Anonymous comments are allowed.
