Didn't need a 4th
I really enjoyed the first three games. Mostly 2. I feel like Shadow Fall was just a game they threw out for the PS4 launch. I found the gameplay at times to be finicky. Frequently got popped out of aiming for no reason. Mantling and aiming over cover was also clunky at times. Not a good variety of weapons. I didn't even see the shotgun pistol until the ending level. You also are locked into holding the railgun having only one slot for other weapons. That being said I really enjoyed the tone of the story. The actual story arc isn't super great but the way they paint the Vekta/Helgan relationship is very good. They show that this war is not black and white and how perspective is everything. The dialogue of the random Helghast talking about not wanting to fight or just wishing they could live in peace is better than the dialouges of the main characters. It's not a terrible game but don't expect too much.
