THIS is how you make first-person shooters. Astonishing single-player. Stunning visuals, surround sound and one-of-a-kind STALKEResque atmosphere. 2034/10 would play again.

Built a gigantic Leviathan machine which burns and bombs everyone around including itself. 10/10 would bomb again
P.S: But srsly, UI is very sexy and outside some performance issues the game feels smooth and pollished.

I have no idea how does it work, but it looks so cool that I just fly around and shoot at things.
10/10 would fly more.

100+ hrs of fun.
