Having the enemies be Nurgle seems like a bit of a letdown to me.
Choosing Nurgle as the enemy forces is a bit of a letdown to me. When thinking of “W40K Enemy in a Hive City that would work in for a wave/hoard-based game”, Nurgle seems like the more boring choice when compared to the other obvious one, that being Genestealer Cultists. I really think they would have been a better choice for several reasons.
Part of what made Vermintide 1 and 2 great was that the decision to have Skaven as the main enemy was something that made it stand out. There are all sorts of games of this type of genre where the enemy is some form of stereotypical choice – undead/zombies or some form of “monster” like enemy (e.g. Mutants). Having the game be focused about hordes of Giant rat men was something that helped show the variety of the Warhammer Fantasy setting as it was a pretty unique choice to have as enemies in this type of game. Thematically it felt better than just generic undead or monsters. Vermintide 2 obviously had chaos forces as the enemy too, but those were in the game along with the Skaven so that was alright.
So to have Darktide seemingly focus on Nurgle stuff seems like it’s instead going for a more generic choice that won’t stand out as much. As someone who knows the relevant W40K lore stuff I obviously know what the enemies are, but to many people they’re just going to seem like typical zombie-like enemies – have a look at the screenshots shown so far, and there isn’t really anything about the enemies that makes you think “this is W40K” in particular. I don’t think Nurgle will really showcase the W40K as much as having Genestealer Cultists would have, terrifying Multi-limbed alien mutant horrors would have been a much more interesting enemy choice than what are basically Zombies. There would have been just as much variety and it would be far less common of a choice that’s more unique to the W40K setting, as there aren’t really many games in this genre that have something similar.
W40K is a massive universe with all sorts of interesting stuff, and out of all the possible choices it’s like they’ve gone for something that won’t really be THAT much different from how you’ve seen Zombies/Undead in so, so many similar genres, TV Shows, Movies etc.
I’m not trying to be negative towards the hard work the developers have done, I’m sure they’ve done a great job and I’ll still play and enjoy the game regardless, but… It just seems like a bit of an uninspired enemy choice in comparison to Genestealer Cult.
