Modder ‘Carl Asami’ has released a new major update for the Fallout 1 mod for the classic Doom games, Fallout: Vault 666. This update adds new content to the mod. So, let’s take a closer look at it.
For those who did not know, Fallout: Vault 666 is a mod that brings a new map, heavily inspired by the first Fallout game, to Classic Doom. It also has enemies and weapons from Fallout.
Update 1.52 adds four new Fallout monsters. To be more precise, it replaces Cacodemons with Mister Handy Security Bots. It also replaces Lost Souls and the Shotgun Zombie with Security Eyebots and Mutant Shotgunner, respectively. Finally, it replaces the Zombieman with the Mutant Pistol Wielder.
This new update also adds new sprites and textures. Moreover, it fixes the Introduction Slide to feature new Monsters. The modder has made a number of visual tweaks and fixes. Plus, he added new ammo and items in various places.
It’s also worth noting that Dogmeat’s AI has been slightly tweaked. For instance, Dogmeat won’t get stuck behind the switch to the Final Boss Room door anymore. Carl also improved its AI so that it can flee from the crushing platform more easily. Dogmeat is now “bright” while sitting, and it can’t enter The Maintenance Room (something that should help its pathfinding).
This is a cool mod that a lot of Fallout/Doom fans may appreciate. So, if you are one of them, you can go ahead and download its latest version from this link.
Speaking of Doom, here are some other cool mods for it. Voxel Doom is a mod that I highly recommend. As its title suggests, it replaces all sprites with voxels. Then we have Aliens Eradication TC which is a must-have mod for all our Aliens fans. A few days ago, we also shared a “Doom 3” Mod for Doom 2. That mod aimed to continue the story of Doom 2, and featured 2 whole chapters, 36 new tracks, and 20+ hours of gameplay.
Brutal Doom: Black Edition is a mod that attempts to bring the art style of id Software’s Doom 3 to the classic Doom games. And how can we forget Brutal Doom? There’s also a cool Doom 64-inspired episode mod that you can download. Oh, and speaking of Doom 64. Doom 64: Unseen Evil is a mod that remakes Doom 1 & Doom 2 to look like Doom 64. Then we have Bloom, a crossover between Blood and Doom. Finally, if you own an RTX GPU, you should try Doom 2 Ray-Traced. Doom 2 Ray-Traced adds full path tracing effects to the game.
All of the above mods are cool, so be sure to try them.
Below you can find the latest developer walkthrough that Carl shared a few months ago. Do note that this isn’t from the latest 1.52 version. As such, it does not contain the new enemies that the modder has added to it.
Enjoy and stay tuned for more!
