Gameliner was the official subscriber magazine of Gameline, an online subscription service for the Atari VCS/2600 game system. Issues were provided free and exclusively to subscribers, despite the $2.00 cover price. (The first issue may have been bundled with the Gameline modem - a required hardware purchase necessary to download games from the online service to the console.)
Along with typical video game magazine features - interviews, q&a, etc - Gameliner also provided a "master menu" list of games a Gameline subscriber could download to their home console. Additionally, a collection of game instruction pages were also included in each issue - essentially game manual summaries with some game strategies and tips thrown in. These instruction pages - along with the master menu - were intended to be removed from the magazine and added to a 3-ring binder originally packaged with the modem.
The magazine lasted only two issues. A newsletter was published sometime during the holiday '83 time frame, billing itself as a stopgap measure, explaining issue #3 of the magazine had been delayed as a result of "printing complications." The third issue would never see the light of day.
