Update: per comment below, Eliminate Pro and Touch Pets Pro are only available in Canada for now whole ngmoco tests their
First-person shooter Elminate Pro [Free - iTunes link] and virtual pet sim Touch Pets Dogs [Free - iTunes link] for iPhone and iPod touch, first shown off by ngmoco at WWDC 2009, have begun making their way into iTunes App Stores around the world (we've confirmed them in Canada, other countries should be getting them soon as well).
Both games utilize the plus+ network for community gaming, with Eliminate looking to bring the classic Golden Eye/Halo style gameplay to Apple's platform, and Touch Pets Dogs, the Nintendogs virtual pooch model. (Sadly, no, there's doesn't seem to be a way to cross over within the two games yet, and hunt the mean soldiers with doggy cuteness -- or vice versa).
The price for both being zero, we're guessing Apple's new policy of "free games can charge for in-app purchases" is having an immediate an obvious effect. Demo without risk, and if you love one or both, they'll figure out levels or gear or powerups or accessories you can buy to enjoy to love them even more.
