Our own Michael Grothaus really enjoyed ZombieSmash when it came out around this time last year. Last week at GDC, I had a chance to speak with Matthias Hoechsman, creator of the game and CEO of gamedoctors, about the title. An upcoming update, which is due out in just over a month, will essentially double the size of the game, bringing 31 new days of stages to play through. Since it's at a prison called "Camp Nowhere," there will be new zombie types to take down and new weapons to kill them with. The update is adding a few new social features as well, including the ability to tweet and share killshots, showing friends how you take out the last zombie in each wave. ZombieSmash will finally get a long-awaited Retina Display update and Game Center integration as well.
The update isn't out yet, but the game's available right now for US$1.99 on the App Store. There are already 31 days of waves to defend against, plus an Endless Siege mode and a Sandbox mode to just play around with. If you pick up the game right now and play through a level a day, you'll be ready for the big update right around the time it hits. Seems like a good deal to us.
