You are Snake Logan, a top-secret operative for the CIA. Metro City is being attacked by mutants, probably released by a scientist called Dr. Mangle. You are on a reconnaissance mission in your Cessna when you are shot down and crash-land in the streets of Metro City. You crawl out of the plane armed with an M60 pulse rifle, and the game begins.
Imagine Billy Blaze with a machine gun, splattering the aliens and turning them inside-out in a nice massacre. This is what Snake Logan is doing. The plot is simple: shoot every mutant and evil machine in the town and rescue civilians. This game uses the second Commander Keen engine made by ID Software (Keen 4-6) - one of the world's best platform-engines in my opinion. The biggest problem is that the game lacks variation, and after ten levels of pure killing and pushing a few switches... you need some time before you start with the second episode.
I have tested the game on many platforms and concluded that the game won't run on some Windows 9x/ME machines. However, it will work just fine in pure DOS and Windows XP (no Sound, try with VDMSound).
