Moxim is a fictitious company that appears in Doom 3, as a corporation that competes with Mixom Corp.
They provide the most expensive products to the facilities of the Martian base of the Union Aerospace Corporation .
The pressure seals provided by Moxim for exterior windows can be replaced with much cheaper cutting costs with Mixon seals, but these are not necessarily safer.
A newscast shown on a television at the beginning of the game (before hell broke loose) reports on Moxim and a rival company called Mixom who sue each other.
Mixom was the holder of several patents for pressure seals used in space equipment and in space colonies. The company sued rival Moxim Corporation in 2145, claiming they were infringing their intellectual property. Moxim proceeded to file a counterclaim.
