Graphics: Excellent graphics no words and no down issues.
Gameplay: As a FPS survival shooter it has it all, honestly only 1 game, it is that stable like this one in this point that is COD. You will have a great experience playing this title, and ofc it is not meant to be easy, it is ment to be wonderful, and grindy.
Controls: Well I tested with controller and without, also did not find nothing wrong, but I made few adjustments because each preset it is different.
---- (Sever Bug) the game crashes and frezze!!!! Stage 1 , Update required.
