With the iOS 4.1 update that added Game Center out in the wild today, we’re seeing an avalanche of new updates for older games that are utilizing these new features. Previously we’ve only seen games that received achievements and leaderboards, but now it seems that three games from Pangea Software are the first to offer real-time multiplayer. Here is the information for each game provided in the press release from Pangea:

[appblurb options=""url="http://itunes.apple.com/us/app/nanosaur-2/id293519917?mt=8" blurb=`Nanosaur 2 is a 3D action-adventure game where you pilot a time traveling pteradactyl from the future.  Previously, Nanosaur 2 was just a single player game, but new in version 2.0 are six new levels and three new multiplayer modes including Capture the Eggs, Battle, and Race.  Thanks to iOS 4.1, users with Game Center enabled devices can now play against each other by inviting friends or using Auto-Match to play against people around the world.  In Capture the Eggs mode players are on teams, and they have to retrieve all of their team’s dinosaur eggs before the other team.  Battle mode, on the other hand, is pure excitement as players collect weapons and blast each other out of the sky.  The race mode also involves a lot of heat seeking missiles, blasters, and cluster grenades, but your primary goal is to race around a track.  Up to four players can play together in Nanosaur 2, and the game uses the Voice Chat feature of iOS so you can smack-talk your opponents while you unleash a barrage of firepower on them.`]

[appblurb options=""url="http://itunes.apple.com/us/app/cro-mag-rally/id281747159?mt=8" blurb=`Cro-Mag Rally is Pangea Software’s caveman racing game where you race primitive vehicles such as the Bone Buggy, Geode Cruiser, Logmobile, etc. around prehistoric and ancient racetracks.  The new 2.0 version of Cro-Mag Rally now supports multiplayer networked racing thanks to Game Center, so up to four players can race against each other using any of the vehicles in the game.  Additionally, version 2.0 is now a Universal Binary app so it runs on the iPhone / iPod Touch and the iPad.`]

[appblurb options=""url="http://itunes.apple.com/us/app/enigmo/id281736535?mt=8" blurb=`Enigmo is one of the all-time best selling iPhone games with well over a million units sold, and it is the winner of an Apple Design Award for Best iPhone Game.  Enigmo is a physics based game where you try to direct flowing streams of liquids to solve puzzles.  Version 4.0 of Enigmo adds a new multiplayer mode where up to 3 players can compete to solve puzzles.  Like Nanosaur 2 and Cro-Mag Rally, Enigmo also supports Voice Chat.`]

We’ve had a chance to try out these new multiplayer features and are really happy with the results. Connecting into an online game is incredibly simple as you can choose to search out a game against random people or very easily invite one of your Game Center friends. The voice chat also works really well, and trash talking while racing against forum moderator Zincous in Cro-Mag Rally was a ton of fun indeed. Voices are clear and there is a mute button if you get tired of hearing how badly you are getting beaten by your opponent.

We didn’t experience any lag while playing, but this could be due to Game Center being so new, and it will be interesting to see how the experience holds up in the coming weeks as more and more games get online multiplayer. As of right now, the Game Center integration in these three titles breaths new life into the experience, and they are definitely worth checking out for the multiplayer and voice chat functionality. We’ll be anxiously awaiting to see what other titles receive the Game Center online multiplayer treatment down the line.
