I'll keep this review short since everything I felt about F.E.A.R. applies to this as well. I'll say it felt like a diet version of the base game, being half the length, half the set pieces, but still managing to cram in all the same beats as the main game.

I enjoyed the new heavy artillery enemy types, along with the machine guns you could pick up from them, not as much the new mechs since they were just tankier versions of the regular mechs. I also got a lot of use out of the laser beam rifle.

It also felt like because the game was so compact, the scares were a lot more prevalent. Partially because the story had escalated to the point where they could be used more, but also because Alma is a constant presence throughout, sometimes frightening you and sometimes saving you. However I didn't feel like this expansion really progressed the story any further, if anything is sort of regressed some of what happened in base game. It mostly feels like this existed to just reiterate some elements that were open to interpretation, sort of like the KH3: ReMind DLC.

Pretty good, but I might hold off on playing F.E.A.R. Perseus Mandate for a bit so I don't get completely burnt out before 2.
