Gravitar is a difficult game, even when you
do know what you're supposed to do. Even though it's not one of Atari's most recognizable games, it's still a true classic. The game is full of tense situations that can turn up the heat at a moment's notice...but that makes it all the more satisfying when you pull off a slick maneuver with the precision of a surgeon,
narrowly avoid danger, and then make a successful escape off the planet.
Yeah, it's that way on PS4 and Vita, too. It would have been nice if they had higher resolution scans and/or converted them to text.
AtariAge has a healthy amount of the game manuals, many of which are also available in HTML format.
There are a few M Network games on the Switch and Vita versions, and on Volume 3 on PS4 and Xbox One.
M Network was Mattel's brand for their line of Atari 2600 games, most of which were adapted from Intellivision games. Mattel also made the Intellivision system; from 1982-1984 almost all the major home video game hardware manufacturers (Atari, Mattel, Coleco, Philips) also made games for one or more competing systems. The recently formed Intellivision Entertainment (Tommy Tallarico's new company) now owns the rights to the M Network games.
