Focus Home Interactive and 3AM Games' Magrunner is an interesting one. It's premise is a little bit Portal, a touch of Half-Life 2, with a heavy dose of Cthulu Mythos dumped into the mix. The game begins in a testing facility, not unlike the one Portal protagonist Chell found herself in. But here the facility is entered by volunteers, who handle a magnetic glove-like weapon of sorts that behaves like part portal gun, part Half-Life 2 gravity gun. As the testing progresses the test subjects find that the facility is changing around them–changing into something sinister. A parallel universe begins to collide with their own, the universe of H.P. Lovecraft's Cthulu Mythos.
