Outlast 2 is an intense first person survival horror and psychological horror game.
You and your wife are investigative journalists venturing deep into the desert in an attempt to uncover the truth behind the unusual murder of an unidentified pregnant woman. Upon your arrival, you find yourself in the company of religious fanatics who perform gruesome and unspeakable acts in the name of their faith. There are some references made to the first Outlast and Whistleblower DLC that you need to know for Outlast 2 to make a bit more sense, so I do recommend playing those prior to Outlast 2.
Armed only with your camera, you are completely vulnerable to enemies. I find this style of horror game more nerve wracking than other games like Resident Evil where you have a way to fight back. You'll need to make use of the terrain, sneak around, and hide from hostiles. If you get discovered, you better run for your life. It is possible to be one shotted, but that only happened to me a couple times. Thankfully, it usually took 2 hits to die, and there were sufficient bandages around to heal yourself after being injured.
Collecting notes, and recording events plays a large role in understanding the the story. Expect to use your camera a lot. Fortunately, you can keep your camera out without it draining the batteries. However, using the camera's night vision or microphone will drain them, so you'll need to scavenge for batteries along your journey.
The night vision is absolutely necessary to navigate through the dark areas, and the microphone is extremely helpful for other areas where your vision is obstructed, like the corn fields.
The game took me about 6 hours to finish, but it would have been closer to 6.5 hours if I had read all the documents while streaming my playthrough instead of just doing it afterwards. It's not a super long game, but the length felt just right.
Ultimately, Outlast 2 is not for the faint of heart. I quite enjoyed the survival horror aspects that made me feel scared, and anxious, but I wish the story had been more clear cut like the first game was. I had a lot of fun playing Outlast 2, but I still think Outlast and the Whistleblower DLC were better and more polished.
