Natural Selection 2 is a mix between a first-person shooter and a real-time strategy game developed by Unknown Worlds Entertainment. The game was designed to be very easy to mod. Lua is not only used as an extension to mod the game, but much of the official game is written in Lua as well. This lets players go in and modify the base game very easily.
