Dark Void is about a chap called William who decided one night (well, it looked like night) to fly into the Bermuda Triangle. This takes him a bit further than he planned, in as much other dimensions can be given a relation to earths in terms of geographical distance. He ends up in a reality that is dominated by a bunch of alien nasties called the Watchers. So, he teams up with a group of humans called the Survivors to beat the blue sluggy snot out of them. He does this with the help of guns and, most notably, a jet pack.
