Doom Remake 4 was one of many fan attempts to bring Doom into the modern age. However, Zenimax has threatened the creator with this scary-looking legal letter:
"Re: Unauthorized Use by ZeniMax Media Inc Intellectual Property
Dear Mr. Vasily: I am writing on behalf of ZeniMax Media Inc.
We have discovered your "Doom Remake 4" game and reviewed the related website, social media pages, and public statements regarding your intent to develop a reboot of the Doom (1993) videogame. Notwithstanding your affection and enthusiasm for the Doom franchise and the original Doom game, we must object to any unlicensed use of ZeniMax Media Inc property. Your current use of Doom IP on its website and social media pages is without our authorization and is infringing. You must take immediate steps to remove all uses of ZeniMax Media Inc intellectual property, including DOOM copyrights, trademarks, characters, artwork, images, and logos and desist from any further use.
ZeniMax Media Inc is the exclusive owner of all intellectual property rights in and to the DOOM franchise. ZeniMax Media Inc does not permit its names, characters, logos, copyrights and/or trademarks to be used without authorization.
Please provide written confirmation by June 20, 2019 that you (i) have removed all ZeniMax Media Inc intellectual property from related websites and social media pages, (ii) will cease all development of the Doom reboot and will destroy all code and materials related to that project, and (iii) will not use any ZeniMax Media Inc intellectual property in the development of any future videogames.
This letter is not intended to be a full recitation of ZeniMax Media Inc's rights or remedies, nor be a waiver of any such rights and remedies, all of which are expressly reserved.
