Doom 3

Doom I Enhanced is a sci-fi FPS game developed by id Software and Nerve Software and published by Bethesda Softworks. It is an updated version of the original 1993 Doom that uses the Unity engine as a shell for the id Tech 1 engine. This game, as well as Doom II Enhanced, was initially released in a suite of classic Doom ports for PlayStation 4, Xbox One, Nintendo Switch, iOS, and Android, however, the ports were heavily criticized on launch due to their poor quality and inaccuracies compared to the previous console generation ports while implementing an always-online DRM that required the player to sign into a Bethesda.net account (meant to unlock Slayers Club rewards) to play the game, despite these ports not having any online multiplayer features. After the initial criticism of the ports, Nerve Software eventually rectified the issues of the log-in requirements and problems with the ports through patches. A PC version of Doom I Enhanced was released through Bethesda.net on January 9, 2020, which was later re-released through Steam on September 3, 2020 and GOG.com on August 17, 2022 as a free update to existing owners of Doom. It was later released through Epic Games Store on August 18, 2022. This game was de-listed from Steam, Epic Games Store, and Microsoft Store on August 2024 as it has been replaced with Doom + Doom II, but is it bundled in the GOG.com release. Nerve Software, with assistance from members of the Doom modding community, would later go onto improve the ports even further by introducing new features, such as official 60+ FPS gameplay, 16:9 widescreen presentation, and free downloadable add-ons with custom vanilla-compatible and DeHackEd WAD support for the mobile and PC versions, among other changes. As of August 18, 2022, all downloadable add-ons are available for both Doom I Enhanced and Doom II Enhanced.
