Pitfall II is one of the few games for the Atari VCS that offers stereo sound. But you need a modded console to enjoy it. Alternatively you can also use the Stella emulator.
Company Information
Activision - the worlds first third party publisher was founded in 1979 by four former Atari employees (David Crane, Larry Kaplan, Alan Miller, Bob Whitehead with Levy, plus founding Chief Executive Officer Jim Levy). Its first products were cartridges for the Atari 2600 video console system published from 1980 for the US market and from August 1981 for the international market. The name "Activision" was decided upon so that the company would appear before Atari in the phone book.
