While I enjoy PTT's arty take on videogame culture, I also enjoy playing games where I get to blow shit up. Or, indeed, shoot monsters in the face.
Never let it be said that we don't aim to please.
Day Traders of the Dead is a Robotron-esque game (or perhaps more closely, a Smash TV-like game -- both Eugene Jarvis designs, of course). WASD to move, mouse to aim, hold the left mouse button down for continuous fire, kill zombies galore.
