Week of Skulls (the GWS promoted event where game using their license have a week of STUFF) is just a few days away.
Fatshark has been releasing a series of countdown videos. With release in September, and a recent Edge magazine interview, most are sure that this is the start of the info dumps.
In the article, they talked about a few different things. I haven't dug deep on it yet but the standout thing was customizable characters. There's archetypes, like the Ogryn, the Guardsmen, the Zealot and the Psyker. But instead of being fixed personalities and looks like in VT, they'll be customizable. In addition to the usual Fatshark RPG elements like which weapon loadout you use, you'll be able to choose their gender and details. So like, helmet, no helmet. Aquila forehead tattoos. Female Guardsmen/Male Guardsmen. (Not sure if there are female Ogryns.....) The way your armor looks. It implies as well that there's no fixed team compositions. If you wanna run 4 Ogryns, run 4 Ogryns.
Not a ton is known to me about the Psyker, other than they'll basically function like Sienna from VT2. Except the "overheat bar" is now "Perils of the Warp."
One new feature though that I'm not wild about....overshields. Sorta like most other FPS, you'll have a regenerating shield over your health bar. The stated reason for it is, in a game with enemies that have guns, they felt it would be too unfair to have them constantly chipping away at player health. So the overshield is there to compensate, making seeking cover and letting your shields regen a feature of gameplay. On the one hand, it'll slow encounters down a little and I like that. But on the other, it's a very familiar mechanic from lots of other shooters, AND I don't really like it from a lore perspective. Shield-tech in 40k games is rather high end, it's not something your garden variety guardsmen or even stormtrooper would have.
So I'd be expecting a lot of Darktide news coming in the next couple of days.
