Prey is a great expansion on the Dishonored style immersive sim. They really nailed the gameplay out of the park for this game. I absolutely recommend it to anybody who likes immersive sims or wants unique gameplay experiences. The ONLY real gripe I have is that the enemy types in this game are not satisfying to me. I enjoy killing mimics and I love them and their design but literally every other enemy becomes merely an obstacle rather than a fun combat encounter.
This game is cool as the devs worked with MeansTV to get it released. The politics are obviously there and it really will weigh on your enjoyment of the game. I just think that this is a very basic hack & slash that is really only carried by the very overt and based political side of it. It is free now though so you should get it cause why not.
