As it turns out, I discovered I had an actual working plan - and design - all ready to write down for this theme.

Bring on the clockwork / steampunk survival top-down shoot'em up, with design taken from everything from Dungeon Siege to Freelancer and Space Pirates and Zombies.

I probably spent far too much time on doing a gear rendering component, as well as a whole modular weapon system, but at least it was fun. Next comes doing all the assets, which are probably going to be all vector designs, though I've got plans for some more intricate ones to go with the classics.
