Valve is running their annual Steam Halloween sale right now.
There’s hundreds of games on sale, though only the spooky ones are currently being highlighted in the sale’s ongoing events. The Halloween sale promo page also acts as a handy list for all the big games currently running limited time Halloween themed in-game events.
Just a few highlights include Prey, Vampyr, Killing Floor 2, Hunt: Showdown, Dying Light, Call of Cthulhu, and Alan Wake. Make sure you browse your wishlist though, as there are other games on sale that aren’t highlighted in the promotion.
The sale runs until November 1st.
