Following the successful launch of Pinball HD for the iPad earlier this year, Gameprom has released a new version optimized for the iPhone 4. Like its iPad counterpart, Pinball HD 4 iPhone combines Gameprom’s Wild West Pinball, The Deep and Jungle Style Pinball into a single game and adds new features including high-resolution graphics for the iPhone 4 Retina Display and new multiplayer capabilities. In Pinball HD 4 iPhone users can challenge other users on the iPhone, iPod touch or iPad over Bluetooth or Wi-Fi in competition to reach the highest score or to complete specific quests. Pinball HD 4 iPhone includes the same general features found in the earlier iPad version, including landscape and portrait modes with full- or flying-table views, a realistic 3D physics and graphics engine, local and global high scores and unique soundtracks with atmospheric music, sound effects and voices. Pinball HD 4 iPhone requires an iPhone 4, iPhone 3GS or third-generation iPod touch and is available from the App Store for $2. The iPad version, Pinball HD is sold separately for $3 and has recently been updated to add the new multiplayer features as well.
