I beat the campaign on the 2nd difficulty in 2016—4.5 hours and I put it down. I replayed it in 2021 to get the 100% as I had 40% of the achievements and am glad I did. I think the main campaign speaks for itself; the 4 arm shooter is very fun.
I had never played the Vendettas campaign before, which was a mistake. I only wish the game actually identified Vendettas for what they are--an entire campaign about the length of the main campaign. I enjoyed the Vendettas characters--I recommend using Jimmy for the campaign as he is the most fun IMO. I also recommend the Hit List, which are kind of like Call of Duty Special Ops missions. Revisiting the same areas is worth it for little extra bits of story and Left 4 Dead style action with surprisingly unique characters--and it's multiplayer too, if you have a friend with a copy. I squeezed 17 hours out of this game and honestly had way more fun than I expected to.
