Finding myself wrapping around from "this game's lore is godawful" to "this game's lore is comedy gold" as I progress through the first DLC. During the base game, it was almost unbearable between the repetition of the mortally challenged joke that somebody thought was the best bit ever, and the Doomguy Was A Feral Human Being Who Ascended To Demi-Godhood stuff that was going on.
I am now finding it funny because UAC facilities deem it necessary to have preparations in place for Doomguy to the extent that they will self-destruct a fully functional base within 5 seconds if he retrieves an item from it. I remember they did something like this in the base game too and having it repeated almost immediately in the DLC made me do a pretty ugly laugh. Samuel Hayden being turned into God and then having Doomguy smash his soul in front of him was another "holy shit this is unbelievably silly" moment, coupled with what comes immediately after. And finally having some UAC intern latch onto Doomguy because he wants to be there when Doomguy kills (presumably) Satan or whatever equivalent exists in this world, it just takes the cake. Such a funny game, whether it's intentional or not.
