The top grossing iOS apps list has been fairly active this week with several highlighted apps stemming from the top 30. Interestingly enough, a majority of the games and applications displayed are those that have appeared in top paid or free application lists from weeks past (not just this week’s).

New Titles Within Top Grossing iPhone Apps List

Call of Duty: Zombies — Santa Monica-based international core games developer and publisher Activision holds the highest highlighted top grossing iPhone app this week. Rising all the way up to #12 is Call of Duty: Zombies. The first-person shooter plants players into the Call of Duty style of play, and bombards them with hordes of the undead that can be battled against with up to four playersvia both WiFi and the Internet (two players via Bluetooth). Currently $4.99, part of its growth is likely due to its being reduced in price last week as part of an Independence Day sale. Its iPad counterpart breached the top paid iPad apps list during that time. Call of Duty: Zombies was last updated in September.

Call of Mini: Zombies — Call of Mini: Zombies is an iPhone title that has been rising steadily over the past few weeks and had risen up the top paid list as well in the past.
