Worms 2: Armageddon for iOS devices will be $1 for a "limited time." The "Battle Pack," an in-app expansion, which adds more weapons and a new single-player campaign, has also been reduced to $1. The game and add-on are normally $5 and $2, respectively.

For a bunch of soil-slithering invertebrates, the Worms are sure getting around in the news this week. On Monday, Worms: Ultimate Mayhem was rated by the Australian Classification Board, though no official details have followed yet.
