3D games on the iPhone? That both play well and are actually interesting? Preposterous! Well, maybe not so strange, but it's rare to see a first person game that actually fits the mobile platform well. Sometimes it's good to be proven wrong!

Vector Conflict: The Siege - Here's a surprisingly amazing game for iPhone: a 3D first person defense title that looks like it came out of the original Tron film. Wireframe tanks, planes and other baddies appear on your radar. Swipe the screen to rotate and face them, then tap to start firing your guns. You can use missiles and a few other items to help protect yourself, but they're limited, so try to rely on your wits and skills rather than big bullets. Between stages you can upgrade certain stats and purchase more ammo. Somehow the 3D aspect really makes this game work, and it's just the right amount of challenge to find and destroy enemy planes before you get hit! Based on the original browser game of the same name.

Mr.Ninja - From the creator of Mr.AahH! and Mr.Space! comes another simple arcade game you'll replay hundreds of times. Mr. Ninja stands on the rotating orbs until you tap the screen to make him jump. The goal is to slash the aliens with each leap and land on the next rotating circle. You can jump in mid-air by tapping the screen again, but other than that, your moves are pretty limited. Which is exactly what makes getting a high score and increasing your combo chain so fun! The free Mr.Ninja Lite is also available.

RoboSockets: Link Me Up - Matching games are no stranger to any gaming platform, but RoboSockets aims to do something just a bit different. The screen is filling with strange robots, each with a number of hands extending to several of the four main directions. You can drop the 'bots anywhere you please, but the goal is to link up four or more robots so they are holding hands (aww!). Hand-holding robots disappear, making room for more of the machines falling from the sky. Simple idea, that's for sure, but the challenge, visual presentation, and variety of robots makes it a big winner. RoboSockets: Link Me Up! Free is also available.
