Wireworks might be the most unique tower defense game I've ever played, with you building up weapons from modules you wire up to different logic blocks. I highlighted it here on GamingOnLinux in early January, but towards the end of January a demo went live.
It's part tower defense, part auto-battling roguelike with a fun blending of ideas. You go through waves of enemies like you would in a traditional tower defense, but each run will be quite different due to all the different wires and modules you'll be hooking up and buying from the shop between rounds.
Such a simple yet brilliant idea, and it's really fun in the demo to make all your weapons dance around the screen to see what kinds of weird over-powered combinations you can make. Nice and accessible too, since it's not even remotely complicated. All the wiring is simply dragging from one block to another, and all the block descriptions are clear so you know exactly what they will do. The effects can be seen before you activate the next wave, so you can try out all sorts of combos before actually engaging in the fight.

Direct Link
The demo includes the first area, along with 70+ items/skills, and 5 unlockable difficulty levels. While the full game is expected to have over 150 different items and skills, 3 unique areas, unlockable characters, more difficult modes and an endless mode.
Love this.
It releases some time in March but no exact date is listed yet.
