Yea even though it’s a cool callback and tie into the series it’s gonna take a lot to explain how the older Predator got the gun back to give to Harrigan in 2. I saw the end animation where the Predators came down but unless we assume they came and wiped them out and kept the gun..which wouldn’t make sense…it just doesn’t work.I enjoyed the film. Lowkey I wish they never done the gun tie in with Predator 2. It doesn't really fit like Predator 1718 story does with the gun.
