Bethesda adds 27-level megawad to its Doom re-release

pcgamer.com:

Bethesda has added one of the best unofficial Doom(opens in new tab) addons to its re-release version of the 1993 classic. Titled Base Ganymede, this megawad adds a new 27-map campaign to Doom set on Jupiter's largest moon.

Unlike many Doom mods, Base Ganymede adheres largely to the style and conventions of the original game, using the base weapons and enemies, but providing different levels to expand upon the challenge originally conceived by Carmack, Romero et al. Its levels also follow the trajectory of the original game, starting out with familiar sci-fi bases, before becoming more surreal and hellish (in a literal sense) as the story progresses.

Base Ganymede was originally created by Adam 'Khorus' Woodmansey back in 2009. Well regarded since its release, it was honored in doomworld's 2012 Cacoawards(opens in new tab). «Base Ganymede is a megawad beaming with personality and charm», said Doomworld's Alfonzo back in 2012 «The maps showcase the Khorus design perfectly in being moderately sized with interesting layouts and monster placement, yet are also very experimental».

If you own Bethesda's updated version of Doom (which is available on Steam and Game Pass), you can grab Base Ganymede simply by launching the game and heading over to the Add-ons section. You'll find a bunch of other classic Doom wad's there too, including No End in Sight, the Plutonia Experiment, and John Romero's own addition to the Doom story, Sigil(opens in new tab).

Of course, you don't have to access Base
