You play Erin a female soldier who rides with her commander on a rag-tag bus trying to escape the demons that have invaded the City. Erin (you) and the other characters take the bus and it breaks down. As an up incoming monster killer, you have to be able to save people as well. Explore the cast of characters and complete their tasks to solve puzzles and play mini-games. As you unlock certain things you will find some of the characters are kind of naughty. You'll experience the hot blonde bus driver showing her goods sunbathing. Or maybe see Erin peel her panties off her hot sticky sweaty butt to take a piss. Big and small details to this game but definitely worth playing!
