* MisaimedFandom: Many know it through the Steam release -- hidden from the public but easy to access if the URL is known -- which was intended as a [[TechDemoGame demonstration of Steam's API]]. Most who downloaded it through Steam, however, were less interested in playing the game than exploiting a security flaw to run cracked games.
* PolishedPort: While the graphics suffer from the "third-party titles can't have black backgrounds" policy, the Platform/Atari2600 port includes various modes that weren't in the original, including "space shuttle modes" which can be played solo unlike the battle modes. (The closest mode to the PDP-1 version is Game 5, and the shuttle mode with PDP-1 controls/hazards is Game 15.)
