I’m not sure I would expect a remaster any time soon. Right now they’re working on a multitude of projects and taking manpower away from that would be a bit counter-intuitive to what they’re trying to do right now. They’re working on Dark Tide, Vermintide 2 content, and they’ve also got their hands in other projects I assume (like publishing). While it may be cool to see Vermintide 1 remastered, I think they’d rather take Vermintide 2 as far as they can go and work on these other projects.
Rather than remastering, Fatshark would likely just integrate the more desirable maps from the first game into the second, like they’ve done so far. The “Back to Ubersreik” maps were all just remastered versions of the originals, but Drachenfels maps were remade (honestly they’re so different they’re less “remakes” and more-so just new maps). I like both, but am definitely in favor of remaking the maps or having new maps. It’s probably a lot funner for the creative teams too, rather than being instructed to just remake things exactly the same.
I think the town portion of Old Haunts that you go through at the beginning of the level is in my top 5 favorite areas in the entire game. It’s beautiful, there is a lot of parkour you can do, secrets, multiple ways to approach the area, and all that jazz.
