You know we always hyphenated Call of Duty as COD and it's weird no one has made more fish puns before this.
Indie developer Ryan Evans has created Cod of Duty, a game that's mostly about shooting fish. The fish are also in a barrel. So, it's not too terribly difficult to find them. Check out the free game for PC, Mac, and Linux. Shoot some fish, let us know how it feels.
