Sony PlayStation

The Sony PlayStation version of Doom was a conversion of Doom and Doom II by Midway, and ran with a modified version of the Doom engine used in the Atari Jaguar port.

This version had several exclusive levels, and added some Doom II monsters to some of the Doom levels, presumably to keep the gameplay fresh. Multiplayer, however, was unusual in that splitscreen was unavailable; two consoles had to be linked together instead. This made the multiplayer truer to the original, but it was done at the expense of accessibility.
