I took the role of a radio enthusiast, intrigued by a strange sound I caught on my receiver. The map showed nothing on the location the signal was coming from, which led me to investigate on my own. There’s a locked complex there, surrounded by a tall wall. I found the correct path by tuning the radio until I heard music, and proceeded to walk in the direction which improves the signal. Soon, I entered a breach, a bubble in which a special radio frequency can be heard. The signal I was able to catch there revealed hints about what to do next. The complex turned out to be a large area, containing other breaches that appear to be tied to certain points in the past. Entering a building, I made radio contact with someone stuck inside the complex after an emergency evacuation. Hungry for more information, I chose to explore further, and try to help my new friend.
The game is fun to play. It hits that point where it's not so easy that it becomes boring, but also not frustratingly difficult. It takes a few trials and errors to figure out exactly what you need to do, but once that's done you can easily complete all tasks.
