Viking Defense. Another tower defense game, with a few interesting twists. And, of course, Vikings.

Corpse Craft is a flash game -- a puzzle/ strategy hybrid that's one part Same Game and one part Tower defense and one part Edward Gorey. Decent art, sound, story and gameplay.

GemCraft Flash Tower Defense goodness. Neat little rpg/upgrading touches in between maps. Lots of maps with some epic bosses thrown in every once in a while. [more inside]

Protector. ~Flash Friday~ Protector takes the mechanics of tower defense games, and adds an RPG element to it. Specialize, level up, and say goodbye to your free time. previously
