Pretty fun at times, pretty monotonous at times. Felt like there was too much backtracking especially during the last few missions. Navigation sucks as a result. Heroic difficulty felt way much easier compared to Reach. I would have worshipped the game had I played it at the time of its og release cuz it's a remarkable thing to make something like this in 2001. My rating would've really been higher if not for the repeated segments in latter part of the game, I understand older game almost always reuse multiple segments via backtracking like resident evil but this felt like the game could've been really short if not for the repeated segments. Music was good I guess but the placement was very random. Also the most satisfying thing about the game is it's shotgun 🤌🏼, had so much fun blasting enemies with it and it's a shame the 2nd game's shotgun sucks in comparison.
