Not too long ago, Zombie Smash developer Game Doctors was acquired by Zynga. Their next game, merging of Zombie Smash with the Zynga casual game machine, the Zyngification if you will, has been announced, Zombie Swipeout.
The good news? It's an interesting game. In our few minutes with it earlier this week, it seemed very enjoyable. It borrows heavily from Fruit Ninja yet makes a few interesting twists on the swipe-things-thrown-into-the-air genre. Then there's the aforementioned Zyngification of the game. You earn coins while playing the game to buy upgrades and progress in the game, yet your progress is limited by your energy level. All of that can, of course, be bypassed by buying in-game goods with cold hard cash.
Wether the game suffers from this paywall method is yet to be seen. Game developers are good, how much and how often you can play are dynamic -- so they can change it at any time. Their goal, of course, is to tune it to maximize revenue. To do that, they need to make sure they don't annoy too many players.
Off my soap box for a bit, the game is actually very well done and I look forward to spending too much time playing it. Unfortunately it's only out in Canada for another week or so for some final testing. But it will be hitting the rest of the world soon enough. Keep an eye out for it.
