New Steam Games Playable on the Steam Deck: Awesome week with The Mermaid Mask and Denshattack! - 2026-07-18 Edition

By

Between 2026-07-11 and 2026-07-18 we selected 14 newly released games that are rated as Verified or Playable on the Steam Deck, and meeting specific criteria in terms of user ratings. Looks like game devs have stopped watching the World Cup as most teams are out and finally decided to ship their games! A LOT of good stuff in this past week - and if I had to pick two, that would be The Mermaid Mask which is an awesome adventure game about solving a crime, and Denshattack! which is a crazy Japanese arcade game where you control a train that gives 90s vibes like very few do.
