*UPDATE* - New "Sensible Size Edition"
Based on the initial feedback I received I've adjust the overall size of the fin. I've tried not to reduce it too much so that it'll still be visible above the water level when you're swimming near the surface. Thank you to all the provided feedback, much appreciated :))

Unlike its closely related cousin 'the land pyro', "The Pyro Shark" is a ferocious aquatic predator. Most commonly found in the warm shadowy depths of 2fort's sewer system, the pyro shark waits patiently for any foolish enough to enter it's waters.

Pyro sharks are now on the brink of extinction due to the increasingly popular use of under water sentry guns being deployed in their natural habitats by sinister engineers. Statistic show that killing 100 engineers has the potential to save a single pyro shark! With your help we can preserve these magnificence creatures for future generations to enjoy. Please do your part. Kill an Engineer today!
