The Edge of Time

You are the chief of security at a remote research facility near the polar caps

on the recently terraformed planet of Venus, having been assigned to a

new project to create an alternate form of teleportation technology that can

allow the user to go anywhere in space-time, including other time periods and

even other universes. Things seems to going perfectly, but perfect never lasts...

As you were taking your daily hike you briefly hear the alarms from the base

and a radio message, A demonic invasion of the base has begun!

You immediately drop what you're doing, whip out your service pistol and rush

back to base, hoping to stop the demons before they get their claws on the

technology.
