Blockade
Maze
Author/Vendor: Catapult Entertainment
Released: 1995
Type: various
Language: English
Premise: The X-Band was one of a handful of 2400 baud modems designed to let owners of various 16-bit consoles play over the phone. One of its "Easter eggs" was the inclusion of two small games that were accessed by a special sequence of gamepad button presses. These were generic to the modem and used its internal hardware, thereby allowing play across consoles. Blockade is a simplistic version of the old "don't cross your ever-growing tail/trail" premise, and Maze is exactly what it says - try to find your way out of the maze before the timer runs out.
Impressions: I'm told that many an X-Band user spent a lot of time playing these two games while trying to find opponents. Their simplicity was their appeal - they were right there, kept your attention for a bit, and could be killed almost instantly once an opponent had connected. I don't suppose that these will ever be dumped due to the nature of the hardware involved, but I'm sure some of the old G/MD hackers out there could throw out accurate clones if they so desired. It might not be a bad idea, as the G/MD public domain archive is still rather small....
