Tried to beat Heartshot but at one point my screen went black (could hear all of the sounds) and had to close it. The autosave is bugged. Whenever I open the game, "continue campaign" is grayed out in the menu. All of the VR settings like smooth turning and grab toggle get reset after every loading screen. There's no way to holster the gun. Dual wielding is super annoying because you have to drop the gun in order to free your hand to open the doors or pull a lever. Then whenever I try to pick that gun again from the floor, I accidentally grab ammo from my belt. EVERY. SINGLE. TIME. I give up, will wait for more patches before playing it again.
The gameplay is decent when it works, the enemy AI is retarded, enemies pose no threat and are easy to kill. The music and sound design is great and the game can be pretty atmospheric at times. Some levels have kind of a maze like design and you can easily get lost but then again it kinda evokes the old school FPS games. The starting pistol is the best weapon in the game, it is much more precise and deadly than automatic rifles, which is really stupid.
EDIT: gave it another try after another patch dropped. VR settings do save now but the autosave feature is broken. I got far into the game and it didn't save so I have to start from beginning
