Just so you know, the 1.0 version of CS2D has been released a few days ago, along with a Steam release. Basically. it's a top-down version of Counter-Strike but with new additions, such as a construction mode, an in-game map editor and Lua scripting.
You can download it through (((Steam))): http://store.steampowered.com/app/666220
The standalone version is still available: http://www.cs2d.com
