I'm considering getting Devour, Deep Rock Galactic, and maybe Dead by Daylight to play with my brother (I haven't played any of these before!) if anyone knows any cool, and perhaps spooky co-op games that are on sale, I'd absolutely love some suggestions! :)

Edit: Some fun co-op games we've played that are on sale are:

Killing Floor 2 (-75% £4.99 / US$7.49 / €6.99)
State of Decay 2 (-60% £9.99 / US$11.99 / €11.99)
Escape Simulator -25% £9.74 / US$11.24 / €11.24)
Dead Space 3 (-70% £5.39 / US$5.99 / €5.99)

We also played Inside The Backrooms which was pretty short but Escape The Backrooms looks similar and is 20% off at the moment, does anyone know how it compares? Thanks :)
