Personally Im enjoying the War Thunder Halloween event. Its just races with weapons disabled, but its silly fun.
Deadlock made the breakable pots into pumpkins and put masks on the characters
Cult of the Lamb has a blood moon ritual that makes everything gloomy and summons the ghosts of your dead followers.
You can harvest them for unique decorations.
The Finals changed some in-game props into jack o lanterns you can throw at opponents to deal damage, and the maps have a spooky variant with spiderwebs and whatnot.
Phasmophobia is running a Halloween event amidst its console release, but it’s mostly just playing the map to make a counter go up, kind of disappointed.
Deep Rock Galactic has the usual lobby reskin, and extra cosmetics, always fun to go back to !
I found the changed atmosphere of the maps in the Phasmo event to be quite spooky. Plus, I can’t confirm, but the ghosts felt like they were acting strange…
Yes I believe they have received buffs on blood moon maps
Dead by Daylight added mystical smoke grenades survivors can use that are a lot of fun - many are suggesting it might become an ability as part of the main game.
Splatoon 3 had the Splatoween Fest over the weekend. Same as last year’s event, just a typical Splatfest but with some spooky aesthetics added.
A lot of games in roblox ;-)
No Man’s Sky has their Cursed Expedition happening now.
Pokemon S/V has a ghost type outbreak, along with Gengar raids.
I think Diablo IV is doing something too, but I have been playing NMS, Pokemon, and planning for IRL Halloween.
I’d say Halo should have a Haloween event.
