So in keeping to my attempt at the one game a month challenge, here is my January submission. The game is free, and has no ads, or in-app purchases.
Gameplay (excuse the slightly low fps here - its due to the recording enabled and my older device testing on)

In zombie contacts you defend against a horde of zombies generated from address book contact names found on your iPhone / iPod / iPad (or use the built in default set of names if you don't want to use your own address book contacts). It is a simple "defense" game where the zombies come at you from the top, and you launch homing missiles at them. There are three difficulty levels, and the more you kill, the faster they come!
I have spent roughly 48 hours creating this game - that includes all graphics, code, animation and the submitting to Apple part! The graphics are all done using Photoshop and my Wacom bamboo tablet. I drew the individual zombies and manually animated them using transforms in Photoshop. Pretty rudimentary, but it works ok for me and a 13 frame animation :)
It is based on cocos2d 2.1. Other tools I used are my trusty Zwoptex for spritesheets and ParticleCreator off the app store for the simple particle effects.
