Not a lot of challenge here. There is no story in the story mode. Overall i really just wanted to burn through the levels because i was a little bored. The guns are fun but i felt like i really would rather play with the melee weapons because that at least made the game a little challenging. Saving was lame and the weapon vending machines were tedious. It looked really pretty. The guns felt good. Collisions with your body and the world made the game feel really buggy instead of realistic. Climbing made me want to delete the game. Been gaming for 35 years, there is no frigging way all these 5 star reviews are real.
