The Taito Channel has a video featuring the Japanese arcade version of Valve's Left 4 Dead. The video looks pretty clean and like the co-op zombie game folks have been playing on their consoles and PC for years.
After the break we've got a GIF of what the game reportedly looks like. Far more clutter on the screen. The only thing missing from the UI is somone popping up and exclaiming, "TOASTY!"
