Fan-made Fallout: Vault 666 takes Doom II on a post-apocalyptic adventure with Dogmeat
The wait for Doom: Dark Ages is worth spicing up with a fresh mod of Fallout: Vault 666, which brings the second installment of id Software studio's series into the reality of the popular post-apocalyptic brand.

Even after almost 31 years, Doom II: Hell on Earth remains highly popular with modders, and interesting fan projects for this classic keep appearing all the time. One of the latest ones worth paying attention to is the Fallout: Vault 666 mod.
The title combines the universes of Fallout and Doom, offering an adventure in which we go to the titular Vault 666 to acquire a hydroprocessor. On the spot, it turns out that the entire shelter has become the target of a hellish invasion. Of course, we might wonder if this could have been avoided if only Vault-Tec had chosen a different number for this facility. However, our protagonist doesn't have time for such reflections; he just grabs a weapon and starts killing demons.
The maps available in the mode mostly use new environmental elements to recreate the interior of the Vault. The weapons were also remodeled in the style of Fallout. Nevertheless, the enemies are sourced from Doom II, except the final boss, which is a Super Mutant.
The mod is well made. In the adventure, we are accompanied by the dog known from FO4, Dogmeat, who greatly helps in the fight. Cutscenes featuring an actor who skillfully mimics Ron Perlman's voice (the narrator for the introductory and ending videos in most Fallout series installments) were also created.
The Fallout: Vault 666 mod can be downloaded from ModDB. To run it, you will still need GZDoom, a project that improves the game engine.
