A simple but solid franchise as Dark Nebula could only give birth to a high-quality sequel, but frankly we didn't expect so many new ideas. The graphics of the game, already excellent, have been further improved and now offer levels rich in details, well defined and unique. Episode Two is immediate and entertaining as Episode One, the tilt controls are very accurate and the action is characterized by a continuous introduction of new challenges to overcome. A must buy.

Iron Man 2 for iPhone and iPod Touch looks very similar to the console version, which is both a good and a bad thing: there are plenty of actions you can perform by using the armor, but the touch screen controls are often clunky and the difficulty isn't challenging enough.

Hybrid 2: Saga of Nostalgia is an action-rpg based on the journey of Gray, a young hero who is looking for a way to rescue his love Fairy. The game could be funny, however there are too many gameplay and technical bugs that ruin the overall experience.

Ozone represents iPhone gaming at its best: it's simple, fun, addictive, cheap and beautifully designed. Moreover, user-created levels make it a virtually never-ending experience.

While remarkable as a meditative and artistic experience, Osmos could not be considered a true winner due to the repetitiveness of his missions and a general lack of excitement for the player.

Need for Speed: Hot Pursuit is a nice racing game, that provides hours of entertainment thanks to a good number of missions. However, the tilt controls seem to be a little inaccurate when it comes to rapidly avoid obstacles and perform powerslides, while there are several things missing from the previous episodes, like car tuning and an online multiplayer mode.

Modern Combat 2: Black Pegasus is an excellent FPS, with nice and accurate controls. The single player campaign is short but pretty intense, while the four online multiplayer modes offer hours and hours of entertainment thanks to the ranking system. Packed with some of the best graphics ever seen on an iPhone, this game definitely rocks. Don't miss it.

It's easy to instantly like The Incident, thanks to its original concept, frantic gameplay and cool visuals: however, the game dramatically lacks content, and the later levels become too much long and monotonous.

Call of Duty World at War: Zombies II is only interesting and nothing more. Nevertheless, for fans and especially for lovers of the genre, Call of Duty World at War: Zombies II remains a valuable opportunity for recreation.

BioDefense: Zombie Outbreak is yet another tower defense for iPhone, in this case with a somewhat original scenario and a very good mix of both interface and controls. What a pity it offers only ten missions and two weapons.

Alive 4-ever Returns is a really funny game, with a lot of enemies and weapons; the co-op mode is potentially infinite and the single player campaign is long and various. However, this sequel is just a "more of the same", without any innovation or difference. If you liked the first Alive forever, you certainly will love this Returns, but If you didn't like it, there's no reason to buy this sequel.

2XL Games is great about the graphics, but still needs to improve gameplay wise; Trophylite Rally is a beautiful, but ultimately boring and generic racing game.

What if Patapon converted itself in a tower defence game? Dinosaur Slayer is a brilliant App for iPhone/iPod Touch with a deep and structured gameplay that lasts for hours of fun and challenge.

Devil Invasion delivers a particular mix of puzzle game and tower defense that works good, with lots of stages to complete and four different spells to cast. Give it a try.

Denki Blocks isn't just a Tetris clone, but it's an original reinterpretation of the generic puzzle games based on blocks movements. The sensibility of iPhone's touch screen gives to the game a fantastic feedback. However, Denki Blocks has a random difficulty level so many schemes are too easy, other are too difficult.

Dead Rising Mobile comes as a boring and repetitive third person action game, with clunky controls and mediocre graphics. It has definitely nothing to do with the original game.

Funny and colorful, De Blob Revolution lacks of deep after few hours of play and has no multiplayer mode to extend the longevity. Still worth a try tough.

Cut the Rope is another App Store hit from Chillingo, and it could be considered as a killer App for iOS devices. A must buy.

With two different campaigns, two modes (standard and survival), a lot of stages and a great gameplay, Crap of Defense is an awesome action game for your iPhone or iPod Touch. The graphic style is also tremendously "trash" and funny. Don't miss it.

Even if it's less polished than Might and Magic: Clash of Heroes, chronoSgear can offer a truly fresh and uncommon experience, that is very different from any other RPG on the App Store. The combat system is clever, while setting and characters are really unusual. With the next updates, we hope Axion Logic will fix the controls and balance the difficulty.

Chopper 2 is a total evolution from the first episode: better graphic, more missions, more variety but the same fun. However, it's still just a simply arcade game; but if you are looking for an immediate and fun iPhone game, it could be the right choice.

A perfect example of how a GDR should be made. Square Enix has managed to develop a deep and involving story with a great combat system and a lot of things to do through the game. Must buy.

Although way better than the previous chapter, Blue Defense: Second Wave! is certainly less ambitious than Red Conquest. It must be said though that even if the game lacks any real additional mode, plot or multiplayer experience, the new units and the deeper control system will satisfy any hardcore gamer that thought the first Blue Defense was too easy.

Blokus is a clever and interesting board game, that will appeal both to casual and skilled audience; besides the repetitiveness, the only problem is that it's a bit too pricey.

More than just a game, BIT.TRIP BEAT is an enjoyable experience that combines sounds and images, encouraging the players to improve their performance through a series of trials. The four stages available in the basic version are well balanced, nice to see and full of sounds and colors.

Sword & Poker 2 is once again a perfect mix between rpg and poker, it delivers also a lot of fun regardless you have played the first chapter or not.

With Monster Mayhem a new kind of action game is born: the Tower Offense. So no passive defense, no war machines set in a battle camp, no position strategy; only violence, weapons and armament management, but of course with smile. Blood and comicality are wisely mixed in this game and if you are bored about the classic "tower defense" games, this is what you are looking for.

It's true, there are too many "ultra arcade games" on the App Store right now, and most of them become quickly boring and repetitive. But Monster Dash is slightly different: though the game keeps the classic "survival" structure, it gives you a health bar, four different stages and a lot of weapons to blast the enemies. If you like the genre, don't miss it!
