Tanks of Freedom

Tanks of Freedom is a turn-based strategy game with gorgeous pixel art. It makes me think of great classic Advance Wars, complete with a soundtrack apparantly made on real Gameboy hardware. Furthermore, it has a campaign with AI players, hot seat vs mode and a level editor. And as a bonus, if you have an Android-based unit there is also a version you can run on it.

Notice the corners? Now that is a complete retro-look. :)
