New Grittier Teenage Mutant Ninja Turtles?

There's a fan-made trailer that doesn't look terrible. It seems to be a thing now to make stuff in that grittier reality based format(not that giant ninja turtles are realistic, but you get my point). Last year they did it with Mortal Kombat. Check out both of the trailers after the jump!

Keep in mind that this one gets a little gruesome.
