Sinister

You wake up inside a strange bunker. You don't know how you got there, and everything seems out of place.
This game puts you inside a dark, creepy atmosphere. Collect items, kill enemies and complete objectives to progress through the storyline.

You can move around using WASD. Interact with objects using "E" and open your inventory with "Q". You can see more info about your inventory items by pressing the number keys while inside the inventory. You can also scroll through your weapons by pressing the number keys.
