   as little time as possible. Select two matching tiles and they will disappear

   its left or right at the same level. Be careful: tiles that look alike
   may actually be slightly different.

We have developed a flexible open source game engine (the OpenRA engine) that provides a common platform for rebuilding and reimagining classic 2D and 2.5D RTS games (the OpenRA mods).
    
      
      The OpenRA mods include new features and gameplay improvements that bring them into the modern era:
    
      
        A choice between “right click” and classic “left click” control schemes
        Overhauled sidebar interfaces for managing production
        Support for game replays and an observer interface designed for streaming games online
        The “fog of war” that obscures the battlefield outside your units' line of sight
        Civilian structures that can be captured to provide benefits
        Units gain experience as they fight and improve when they earn new ranks
      
      
      OpenRA is 100% free, and comes bundled with three distinct mods. When you run a mod for the first time the game can automatically download the original game assets, or you can use the original game disks.
