You know what's tougher than a shark? A papercraft shark that somehow manages to survive in water. I'm impressed.
Hailed as the "best looking new game I've seen so far this year," by Destructoid writer Jonathan Holmes (ha ha Holmes, I have written proof in an email, you can't sue me!), Derrick the Deathfin is described as "illegitimate lovechild between Sonic the Hedgehog and Ecco the Dolphin". Expect to see it on PSN sometime in summer 2012.
