Diggers (1993)(Millennium)(NTSC)

One of the best games on Amiga CD32. You are in charge of five units of chosen race that are competing against each other. The main goal is to reach certain amount of mined gold/diaments or to kill enemy that can be done by flooding tunnels of opposing team or direct fighting.

I recommend using WinUAE emulator with appropriate ROM's or FS-UAE.
