Hi,
I'm Jack Powell, I have ported LaserTank to run on iOS (iPhone, iPod and iPad). It is available on the App Store.
You can also search "LaserTank" on the App Store to find it. This is a work in progress and the code is ported exactly as is. The difference is that I got to add some GUI elements in order to pick a level, new game, undo etc. the list goes on.
As far as I know it is fully functional for what it is, it does support the existing LVL file format since it is a direct port of the PC version. I made a PC version but I haven't released that one yet that uses full Direct3D 11 rendering and a Macintosh version to use OpenGL.
If anyone wants to give it a try please let me know what you think.
