Beautiful 2D platform, with amazing soundtrack but very short story
The game puts you in the shoes of the badass Hardboiled Chicken (called that because it's egg was boiled before it was born). You join a Rebellion against the bad penguins who want to destroy the world. Basically you have to solve puzzles to progress in the game with the occasionally gunfight. I say occasionally because even though there are many enemies to kills they don't really pose a treat. There are also three levels with jetpack action that are really cool and breaks the pace of the game a little.
Graphics are amazing, the scenery is very detailed and the game runs very smoothly, meaning it's a joy for the eyes. The soundtrack in the game is also very good, and I would say one of the best in 2011 (probably didn't win any prices because it's not a very known game), and all music is done by a group called New World Revolution.
There is also a local co-op option for the game, which puts you in the shoes of two small birds that have to rescue the general's daughter. You basically play trough the same areas of the single player game, but with some co-op puzzles to solve.
As far as trophies go, it's an easy platinum, even though some of them are not well described. For example, there is a trophy that requires you to kill 300 penguins, they don't say 300 in one play through.
