Cold Alley is an action flight simulator, whose campaign takes you on "unwritten covert operations" from history. For a Windows 8 game, it is nice to look at and offers a fair bit of content if you care to play it as intended. If you are reading this however, you are most likely looking at how to get the achievements. If you play it solely for achievements, be warned: 95% of your time will be spent grinding towards your 10,000 kills.
Start off by going to the tutorials to learn how to play the game. You only really need to know how to do the basics, as you won't really be playing the game all that much. Completing the first five tutorials will give you five achievements for 50.
Now you know how to control your plane and fire your guns, start up a Capture the Flag match on any map. Capture the enemy flag for "Flag Capture" and return your own for "Flag Return." Exit the game once you have both of these.
Now start up a Defend The Base match and go straight for the base to destroy it for "Enemy Base Destroy." Exit the game once you have it.
Now all you have left is the "x kills" achievements. Start up the campaign and get through the first mission. The second mission, you will be the gunner in a helicoptor and there are around 130 enemies to kill. Keep on playing this mission or segments of it (see the guide for more information) until you have your 10,000 kills to complete the game!
Cold Alley is a decent game that is let down by a very disappointing achievement list. As an achievement hunter, I just wanted to get the game done as soon as possible, but with a more imaginative list I would have seen much more of the game. As it stands it is a very easy, but very dull completion unless you want to take much, much longer getting kills from dogfights.
