Pretty much the most well known thing I've done due to the fact that part 2 was featured on Newgrounds.com for a month or so. The story goes like this: Talhasha, a mage from Dungeons and Dragons times, has come to the future to conquer it. Only SWAT Princess and her elite special forces catfight training can stop her. There's an interactive function on part 2 that allows you to pick the winner.
FLASH
Part 1
Talhasha arrives in our dimension to beat it up with magic.
SWAT Princess strikes from the shadows. Ass kicking to follow.
Part 2
The climactic second part! Where the fate of the world is decided by your
preference in breast size...as it should be.
