One we missed from earlier this month, Pacify is a very popular survival horror and the developer has been making improvements ready for the Steam Deck. It has a Very Positive rating from 23,297 user reviews, so it must be quite something.
Released back in 2019, the developer released an update on February 7 to include various optimizations for the Steam Deck. They say at Medium quality you can expect a smooth 60FPS while playing which sounds ideal. They also included this nice shot of it running on Deck:
Not sure how I feel about playing something like this on a Steam Deck. It's bad enough sat at a PC, what if it makes me jump and I throw the Deck out of my hands? Oh gosh.
If you've never seen Pacify before, the trailer is below:
You can find Pacify on Steam.
