It is mouse and keyboard. There are only 2 times in the game you have run from monsters. I just hid behind a rock until the one went around the corner! Otherwise, it is exploring, developing the story and puzzle solving. You move from a blizzard to underground caverns to a deep sea voyage in a submarine to a dilapidated mansion to shifting sands under the desert... very rich and varied environments.
In my PC corner for the winter, gaming, knitting and reading.
