What do you get if you cross a catapult, a flock of furious avian, and an army of evil swine? If you're answering anything but Angry Birds then you've obviously been living under a rock for the last 4 years.

Angry Birds is Roveo Entertainment's popular gaming franchise where you must catapult a selection of very angry birds straight at a group of sinister pigs and try to cause as much damage as possible with each shot. Personally I played the first few levels of Angry Birds and got a little bored, but then I purchased a T-Shirt featuring a furious Yoda bird and my interest in Angry Birds: Star Wars was piqued.

Angry Birds: Star Wars is a spin off to the popular franchise that plays remarkably similar to the original, but with an ingenious Star Wars spin that increases the fun ten fold. Whatever storyline you have is told through a series of static pictures that seem to mimic the popular scenes from the Star Wars movies, but without dialogue. All things considered this is not a game where the storyline is particularly important; or even relevant, if you stop to think about it.

Essentially Angry Birds: Star Wars follows the same set up as the main Angry Birds game. It is a Worms style strategy game in which being able to observe the games physics engine is essential to your success. At the start of a level you will be given an overview of the evil Empire's fortress, and you will then zoom in on your first bird sitting in a catapult. You have to pull back the catapult; select your ideal angle, and fire the bird at the imperial swine. Whatever damage you inflict will rack up a few points, and the level is concluded once all of the pigs are KO'd. At the end of each level you will awarded mega points for each Angry Bird that you have left standing. To be honest the majority of the early levels can be completed on the first attempt, but then the game grades your results. It then becomes an addictive challenge trying to earn a 3 star rating on each level, and this is where the tactics come into play.

In this Star Wars version of the game each Angry Bird will feature a unique ability based on the Star Wars universe. This can range from Luke Skywalker's single light sabre swipe through to ObiWan's ability to push distant objects with the force; with a quick check in for Han Solo's ability to shoot distant objects with his blasters. Each of these abilities must be activated once the bird is already hurtling through the air, and so utilising them to inflict maximum pointage can be a cunningly complex process.

Further challenges can be unlocked in later levels as the characters blast into orbit and the birds are catapulted across a zero gravity landscape. Some of these levels feature small planets and you have to figure out how their individual gravitational fields will effect the path your bird will take. There's even one level where an evil pig version of Darth Vader will use the force to prevent you from moving certain objects in his surroundings. So all things considered this Star Wars atmosphere increases the tactical nature of the gameplay and contributes to much of the ensuing funnage!

Graphically speaking the game does a decent job of maintaining that atmosphere. Like the original Angry Birds: Star Wars looks very similar to a game like Worms. The Angry Birds; and any interactive objects, exist on top of static backgrounds. These can range from the deserts of Tatooine, through to the icy depths of Hoth, and even into deep space. Both the birds; and the imperial pigs, have been re-created with some wonderful outline sketches that are wearing hilarious Star Wars costumes.

However It is the games sound that sealed the deal for me. The angry squawks remain present and correct, but are here joined by a series of brilliantly rendered Star Wars sound effects. Both blaster fire and light sabre vroom's have been recreated wonderfully, and there's a sinister laugh from the Darth Vader pig that must be heard by everyone.

So overall this is a fantastic little strategy game that will appeal to any Worms fans looking for a single player experience. The Star Wars makeover really heightens the atmosphere to take a mildly diverting game and create an insanely addictive experience.

It is currently available for all Android devices as either a free download with frequent ads; or an ad free version that costs just a few pounds. It is also available for £10 on the PC, but I can't imagine paying that price for it when there's a complete free version available. The game is easily worth a tenner, so is easily worth a few pounds also. The free version can get a little irritating as it constantly advertises the Croods game every 3 times you attempt a level, so you're probably best off paying the price for the ad free version. Whichever you select be assured that you will not be getting much else done until you have mastered each and every level that the game has on offer.
