TactiX is a unique tactical experience with a huge variety of maps and gamemodes. If you play the default gamemode called "Deathmatch" your task is to destroy the map in a way that you are going to be the last player standing on top of it using 11 of (currently) up to 46 unqiue skills. If you fall into the abyss then you can't win the round anymore but you can still influence the game with your abilities. The final game will also going to offer a huge modding API so people can easily add their own gamemodes, skills, blocks and other features.
This is the launcher used by TactiX which automatically downloads the game and keeps it up to date. Copy the launcher into an empty folder and run it. Requires Java 1.7 or newer to run.
