If that doesn't scare you away however, you can buy Viscera Cleanup Detail for $7.99. RuneStorm notes that the price will increase down the road, so if you want to save some money and go for the metaphorical fixer-upper car over the shiny new one, Early Access may be for you.
It's true, nothing cleans up blood and viscera off your floors, walls and PC quite like steam. Erm, not that we would know, officers.
