Cyndefense 2 is going to have one last major update before I start working full time on other projects. Bug fix updates may still occur afterwards as bugs are discovered. The final update is going to add in a new map or 2 as well as some new controls for directional towers. No release date for this update yet, but the goal is to have it done before Christmas.
With that said, this is also the official announcement of Cyndefense 3: Incyneration :)
