Gabriel Leoni, the artist behind this tease, is apparently just as sick as everyone else waiting for Valve to announce Half-Life 3. For $15 at 72Pins, you can claim to own a copy of Half-Life 3…sorta. As a proud owner of the Half-Life 3 NES cartridge, you can spread the tease to your friends and loved ones. But, on a more serious note, how awesome would it be to play a retro version of Half-Life with the Nintendo light gun?!
