There is actually a social networking site called The Great Games Experiment (GGE), so I'd be happy to put up Penguin Arena.
EDIT: Since Penguins Arena was made with Torque, you may recognize GGE, as GGE is a project from GarageGames.
DOUBLE EDIT: Woops, you do know GGE, as you have a profile there. Woops, I didn't realize code FPS was Penguins Arena, so when I searched for "Penguins Arena" nothing came up.
Anyhow, this is what I came up with: http://www.greatgamesexperiment.com/game/penguinsarena
