There are some interesting gaming tidbits to report on today from the world of iOS:

Infinity Blade 1.3

[ad#Google Adsense 300×250 in story]At long last, the update Infinity Blade players have waited for has arrived! Version 1.3 adds a new content pack and multiplayer capabilities. You can now challenge friends through Game Center.

Infinity Blade is an amazing-looking medieval action game in which you must hack and slash your way through enemies to finally square off against the God King. It’s built using the Unreal Development Kit (UDK), the same technology used to create phenomenal console games like Gears of War 2.

For a limited time, it’s 50 percent off, too – $2.99 for a universal app that runs on the iPhone, iPod touch and iPad.

Chaos Rings Omega

Square Enix has announced the release of Chaos Rings Omega, the prequel to Chaos Rings, an RPG available for iOS. When we say “prequel,” we mean it: this installment of the Chaos Rings saga takes place 10,000 years before the events in the first game. It follows “the story of Vieg, who has been summoned to the Ark Arena to fight to the death, and experience the events leading up to the original game.” It features a turn-based battle system, “solo” and “pair” moves, and the ability to collect “genes,” which let you equip your players with monster magic and special attack moves.

Chaos Rings Omega available for $11.99 for the iPhone and iPod touch and $14.99 for the iPad. (The original Chaos Rings is now on sale at a deep discount, $3.99 and $4.99 for the iPhone and iPad versions, respectively, down from $12.99 and $15.99, respectively.)

Puzzle Sphere debuts

Funpause was a casual game developer with deep roots in the Mac community, creating titles like Atlantis and Fairies before they were acquired by Big Fish Games, eventually producing the Azada series for them. Now they’re back as indie developers on their own, under a new imprint – Puzzle Brothers – with a new game, this time for iOS: Puzzle Sphere. It’s a $1.99 universal title for iPhone and iPad in which you guide your sphere around 64 levels of switches, traps and more.

Dark Nebula soundtrack

1337 Game Design has released the soundtrack for its game “Dark Nebula – Episode Two.” Composed by Swedish musician Calle Hansson, the soundtrack garnered the attention of British record label Hunter’s Moon, which has made it available on iTunes.
