I recently replayed this and played 2. They are both good, but this one made me feel so cool when I did well. The levels are all designed to be challenging and to make you feel like a god when you win. The horror isn't very strong, but has some moments of decent atmosphere.

Some good tension and horror scenes separated by unremarkable modern military shooting and a kinda shoehorned-but-necessary bullettime mechanic. The bones of a good game are here but it's such a product of its time in some unfortunate ways.
