This game will forever hold a special place in my heart for a lot of personal reasons, even if I'm fully aware that basically everything immediately following 343 Guilty Spark sucks and badly reuses past levels. Even despite that, the fact that this game was released in 2001 for a brand new console and still has enemy AI that's smarter than most shooters coming out in 2021 blows my mind.

Don't play with the Anniversary graphics, they ruin the original atmosphere and art direction.
