The game has quite a good amount of work put into the artwork as well as gameplay, while maintaing an average storyline. I personally feel the sounds used as well as choice of music is simply brilliant! I've found myself hearing it when not gaming quite often. I finished the game within 3 hours and feel that there is a good pace between the jetpack missions along with the standard shoot em'up style of gameplay. Some of the gameplay elements such as controlling the enemy through bots is quite ingenious and will make you think why is the AI making an infinite amount of penguins spawn on the door.
However, a couple of things did leave a sour taste in my mouth which can put off some buyers such as
> the missions are quite repetitive in terms of what to do. Find a keycard and unlock a door; not only does this get stale after a while, but some of the missions require puzzle solving skills (getting crates from around the mission, planning how to get them over eachother' which can turn away people wanting a pure run and gun game
> there is little variety between the guns. There are 3 weapon classes with only 2 weapons in each class, and two throwable weapons (ones that can allow you to control enemies and grenades) Considering the lenght of the game though, I do feel its quite justifiable.
Not really a complaint buy some people may not like the fact that the game is a windowed game.
If you can look past these quirks though you will find an intriguing game of killing penguins as a chicken with grenades and guns. I do feel though I should note that I got this game in a bundle, so I did not pay anything near full price for it, and this can impact the way I do feel about the game.
I hope this helps, and thanks for reading!
