Despite it clearly saying on the box "OFFICIAL ARCADE VERSION", I... can't find an Arcade version. I suspect like Deep Scan it had a slight name change before being brought to the 2600, but unike Deep Scan, finding information on the internet is really really difficult. I'm not even entirely sure an arcade version existed (since it is an extremely simple game), but any ideas? -Black Squirrel 14:33, 29 May 2010 (UTC)
