Chillingo’s Anomaly 2 ($5) has arrived on iOS after debuting on the Mac earlier this year. The graphically intense tower defense game has an online multiplayer mode which lets gamers play as the alien towers or attacking humans, as well as a standard offline single-player mode with “one million tactical combinations,” according to Chillingo. We’re pretty blown away by the fine detail on the Retina displays of iPads, and although the gameplay is very similar to Anomaly’s, developer 11 Bit Studios has added the ability of units to transform into different configurations for specific situations such as long- or short-range attacks, plus some other tweaks. It’s a very cool sequel to the prior Anomaly titles.

Cobra iRadar (free) from Cobra Electronics Corporation has a revamped map and a number of new features. A follow-me mode makes it easier to see alert locations on the road ahead. Simple navigation options and live traffic info have been added, as well as map controls and a macro map view. Some of the app’s features are only accessible when using a Cobra iRadar Detector.
Google’s Google Search (free) has updated to version 3.1.0, adding many Google Now features, including notifications, reminders, new cards, and handsfree voice commands. Google Now can remind users to complete certain tasks at particular places or times, and reminders can be very specific.
Evernote’s Penultimate (free) has been updated to version 5.0.1, adding the ability to use the app with the new Jot Script Evernote Edition stylus by Adonit, which we just reviewed. The app also uses new gestures, including pinch-to-zoom and drift, which scrolls as you write. Penultimate also now boasts “improved wrist protection to support any writing style,” although we’ve had decidedly mixed results with that during our testing of the app.
