Doom II

Doom II, also known as Doom II: Hell on Earth, is a 1994 first-person shooter game developed and published by id Software for MS-DOS. It was released on Mac OS the following year. Whereas the original Doom was initially only available through shareware and mail order, Doom II was the first Doom game released initially in stores.

Doom II features larger levels, new enemies, a new Super Shotgun weapon, and a new power-up. Master Levels for Doom II, an expansion pack with 21 new levels, was released on December 26, 1995. Another expansion, No Rest for the Living, which adds nine extra levels, was developed for the release of the game on Xbox Live Arcade and is also included in the Doom 3: BFG Edition, as part of Doom Classic Complete, and as a free add-on for the 2019 Unity engine port of Doom II. It was also included in the 2024 KEX Engine port.

Doom II received positive reviews for its refining of the original Doom. It has sold more than 1.8 million copies, has earned over $74 million in revenue in the United States, and is considered one of the greatest video games.

Doom II was ported to the Game Boy Advance in 2002, Tapwave Zodiac in 2004, on Xbox Live Arcade in 2010, and on Nintendo Switch, PlayStation 4 and Xbox One in 2019. The release of the Doom source code has facilitated ports to platforms including iOS and other cellphone systems. Doom II was included in the Doom ports for the PlayStation and Sega Saturn in 1995 and 1997.
