The mobile port costs $5, which is cheaper than on other platforms. It follows the previous mobile title Stranger Things: The Game, which debuted alongside the second season and was a freebie. It seems you can get together with your friends for local co-op this time around, and you might be able to hook up a controller to play Stranger Things 3 instead of using touchscreen controls.
If you're still as hungry as a demodog for more Stranger Things games, Netflix is far from done on that front. It's planning to release a mobile RPG next year.
