Wendland TD is a German Tower Defense like game. In this game, the player's goal is to stop a truck or train (you can choose between a street or rails in the main menu) by placing obstacles like garbage, cows, or other trucks on the road/rails. This game is only available in German, because it is related to events that are actually happening like this in Germany.
Liquid War 6 is an original multiplayer wargame. You have to control an army formed with thousands of pixels that look like liquid, and try and eat your opponent. This is a total rewrite of the (now quite old) Liquid War 5 version. It's still in beta stage, with many imperfections and no network play but it's playable now.
