Anomaly 2

The style of the gameplay has been described as "reverse tower defense," "tower attack," and "tower offense." Players control a convoy of vehicles investigating anomalies around sections of a downed alien spacecraft, which are protected by various types of defensive towers that must be destroyed. Players do not directly control the vehicles in the convoy; instead, they set paths for the convoy to follow along city streets, while also dropping power-ups such as decoys or smoke-screens to aid the survival of the convoy. In addition, players can purchase and equip several different units with varying offensive and defensive attributes to make up the convoy.

In the Windows, Mac, Linux and XBLA versions, players directly control a soldier on foot (dubbed the Commander) who they use to pick up and drop the power-ups for the convoy. The iOS and Android versions omit the Commander in lieu of the player directly placing power using the touch-based interface. In addition, the iOS and Android versions do not feature the levels set in Tokyo.

The game is set in the near future, where sections of an alien spacecraft have crash-landed in several major cities around the world, including Baghdad and Tokyo.

The player assumes the role of the commander of an armor battalion (referred to as "14th Platoon" in the story) sent to investigate anomalies that have occurred in the vicinity of the wreckage and gather information on what is happening in the affected areas, as the anomalies are interfering with radar and satellite imagery - and to neutralize any threats that may exist within the anomalies' field of influence.

Anomaly: Warzone Earth received strong reviews from critics. GamesBeat gave the game a score of 80/100, saying, "While it's hard to control, Anomaly is still playable and enjoyable as long as you take the time to master the interface first." Select Start Media awarded the game 7.9/10, praising the unique idea of "tower offence" and solid gameplay. As of November 14, 2011, the iOS version is one of the highest-rated iOS games of all time on Metacritic with a score of 94.

In June 2011, OS X version was awarded the Apple Design Award during the Apple Worldwide Developers Conference. At the end of 2011, Apple posted their annual iTunes and App Store rewind lists, where Anomaly: Warzone Earth was named Game of the Year Runner-Up.
