Mattel Electronics, the maker of the Intellivision, sold its Atari 2600 games under the M Network label, and most of them are listed on that page. The two games here are Mattel 2600 titles that were finished around 1983 but shelved, partly because they needed two players. Swordfight is Stephen Tatsumi’s duel between two large knights with laser swords. Sea Battle is a cut-down conversion of the Intellivision naval war game. Intellivision Productions finally released both on cartridge in 2000.

Swordfight is a two-player duelling game for the Atari 2600, designed and programmed by Stephen Tatsumi at Mattel Electronics in 1983. Mattel finished it for its M Network label but never released it. The game finally came out in 2000, when Intellivision Productions made a small run of cartridges. Two knights face each other with laser swords, and the fighters are far bigger than almost anything else on the console. You can play it here in your browser.
Sea Battle is a two-player naval war game for the Atari 2600, programmed by Larry Zwick and Bruce Pedersen for Mattel’s M Network label. It is a cut-down conversion of Mattel’s 1980 Intellivision game of the same name. The 2600 version was finished around 1983 but never released at the time, and its working title was High Seas. Cartridges only appeared in 2000, in a small run from Intellivision Productions. You can play it here in your browser.
