I've not downed to the trend so no hand-drawn sketch
Here's what I've modeled so far. I consider no part as finished at the moment, so everything is subject to change.
I'll go for a lot of blades and spikes, and also some miniguns. The side seat will be rear mounted to allow the copilot to kill zombie backwards, just for fun. The front minigun is supposed to be controlled by the driver with an helmet attached device.
PS : The DB9 is just on hold, I will resume work on it after the contest, as I don't have enough time to work on both projects at the same time.
