Definitely not a game for everyone.
Signal from Tōlva is an FPS game with some light progression elements in it and semi-open game world. It is, however, somewhat light on the FPS front, as the vast majority of the time you'll be running around exploring, finding and scanning stuff. The game has a pretty nice ambient soundtrack, which should tell you much about the focus of it. If you're expecting an FPS game with tons and tons of non-stop action, then this is not it.

With that said, the gun play is actually pretty nice, when it does happen. There is not much variety to weapons or enemies, but it's alright. The game is very short. I've got 11.5hrs and I've finished both of the campaigns on hard, whilst searching out everything on the maps.

I found the game quite enjoyable, because of its atmosphere, great soundtrack and somewhat slow paced exploration, but then again, I am quite the sp erg (why is this censored!? Am i offensive to you, steam?).
