UPDATE: PopCap Games sent me a note that their update has been delayed till mid-June. Ah well, so many zombies to take care of anyway…
Com2uS has released what they call the “definitive tower defense game”…Tower Defense: Lost Earth. Available for iPhone, iPod Touch, and iPad, Lost Earth has players journeying to the future with the last expedition from earth as they battle to gather resources and defend humanity on a hostile alien planet with endless waves of enemies. With over 40 campaigns, 6 challenge maps, and 5 world maps encompassing mountain ranges, ice lands, lava terrain and more, Tower Defense: Lost Earth includes 4 game play modes, 10 types of enemies, 4 weapons and up to 9 tower types, with many more in DLC upgrades coming soon. Tower Defense: Lost Earth is available for $2.99 for iPhone/iPod Touch and $4.99 for the iPad.

PopCap Games has announced a major update that will happen in mid-June to its immensely popular game Plants vs Zombies for iPhone and iPod Touch. The flower defense game pitting zombies against the powerful vegetation features additional content, mini-games, and achievements. Included in the update is the Zen Garden to the mix, wherein you can now raise your own plants for coinage. More updates are promised for later in the year, but as always these are all free.

Ricky Carmichael’s Motocross Matchup has also received an update. The free-to-play racing title is based on the motorcycle racing career of all-time champion Ricky Carmichael, and includes a full motocross racing experience complete with GameCenter-supported online play and voice chat, graphics with full retina support, and tons of customizations for your bike and ride. The update adds in retuned pricing schemes, unlimited gas for unlimited racing, and many player requested fixes. You can dowload the update through the iTunes App Store.
