Mars War is a 32 level megawad for Doom II created by Nathan Lineback.

Mars War started off as an old WAD on The Library of Trantor BBS, which eventually stopped operating. This WAD was updated and completed after the author's multiple dealings with Microsoft products.

The story starts off with the player, a lone Martian terraformer, lost in the middle of nowhere. A terraforming project has been lead by the United Organizations of Earth. The organization has threatened to take over. The recent events have prompted an invasion from Earth, but something went wrong with their ships, capable of "space-warp". Those ships were built by a company with the initials "MS".

The megawad is anti-Microsoft, the biggest clue to this being the final level, where the demonic visage of the final boss is replaced with an image of the face of Bill Gates as a Borg. The starting room of the level is also in the shape of the Internet Explorer logo. The god mode face is replaced with that of the Tux, the mascot for the Linux Operating system.

Three of the levels in this megawad are Doom II conversions of 1994 levels due to mapper's block. They are MAP15, MAP20, and MAP25, which are conversions of MOONBASE.WAD by Curtis Turner II, Heretic E1M1, and 11BONES.WAD by Damon Brodie, respectively. This only to affect in version 2, while the version 3 or later will get released originally.

The megawad was finished and released on the author's personal website in 1998. However, it was not on the idgames archive until 2003, when it was uploaded by Xaser. Version 3.01 only to be uploaded in the author's personal website, but all the speedruns, will not to be updated.


The full story line is not important, but here it is anyway.

It is a thousand or so years in the future and you are a Martian terraformer stuck in a small station in the middle of nowhere.

Since the beginning of the terraforming project, the United Organizations of Earth have been threatening to take control. They do not like the independence that Mars has gained and view Mars as a threat.

The United Organizations of Earth are an accumulation of all governments, large corporations, and corporate owned governments of Earth. For over a hundred years they have tightly controlled the population of earth, at an almost microscopic level limiting what they are allowed to know and what they may do.

A few months ago, a huge number of radical, highly educated people escaped UOE persecution by coming to Mars in a large space-warp capable ship they built more or less by themselves without the knowledge of the UOE.

This was the last straw for the UOE. They attempted to quickly clone the space-warp technology and sent off an invasion force.

Only something went wrong with their new "space-warp" capable ships...


Version 3.01 has a many big features to improve the DOOM II gameplay. All the remaining features from version 2 is same as original DOOM II.
