Mondo Medicals is a first person puzzle game, where you've signed up for a research program to find the cure for cancer.
You need to pass a few tests before the research can begin, but the tests get progressively more and more bizarre, and the instruction videos that you get to see in between tests makes you suspect that something very wrong is going on here.
A walkthrough can be found here:
