Well what can you say - at 9.99 this is a complete bargain ! Still worth double that now - this game is clean, graphically immense and so in depth.
An vary wide range of weapons and plasmids to choose from and in game tests to enhance those weapons its just truly addictive and you won't be able to put the game down.
Don't get me wrong there are times when this game will truly leave you frustrated but thats the beauty of it , many games nowadays are just not challenging and this will have you pulling your hair out, thinking and test you from start to finish.
Don't think i could of sold this more to a gamer that likes their shoot-em-ups, a challenge and generally a well made, thought out game.
