This Portal clone was supposedly built in just 3-weeks, with Unity — basically an integrated authoring tool that enables developers to create 3D games on the iPhone. Video after the break.

For your information, they [Valve] don’t seem to bother about us doing a prequel for Portal. They’re even sending us their congratulations and they seem to enjoy what we’re doing.

Bootant’s Crazy Choppers for the iPhone / iPod Touch crams five locales, tilt controls, and a weapons upgrade system, into a soon to be released $0.99 App Store game. Plus, the controls “can be calibrated at any time during by pausing the game.” Video after the break.

While flying around, you need to carefully keep an eye on both your health and fuel gauges. After the first few levels, enemies start firing back, forcing you to take evasive maneuvers and multiple attack runs to avoid enemy fire.

For $4.99, the Dirt Moto Racing iPhone / iPod Touch game features “a pounding 12-song soundtrack, online leaderboards, 21 unlockable achievements, 36 unique game events, and customizable rider and vehicle.” Video after the break.

In all, it’s really a great game that offroad racer fans have reason to embrace. The controls feel “right,” the physics are solid and it’s just a great off-road racer that stands as the king of the genre in the App Store.

Check out the video to see how it plays. I tend to find it hard to recommend any tap shooters, but this one carries some familiarity that some may enjoy.
