I saw this game a long time ago and wanted to start it up again. Here's how it works.
It's just like Picture Wars, where you post a picture that defeats the picture posted above. The difference is that here you have to draw it yourself and post it via an image hosting website, like Photobucket.
I'll start it off with a picture of a stick figure holding a sword, which I drew in roughly 15 seconds.
In the original Doodle Wars, nukes were not allowed. This rule makes sense, so I think nukes should be disallowed here too. Now to beat the above image...
There is a rock containing the rules of Doodle Wars, where one of them says No Nukes, rendering your bunker unnecessary.
