The very cool tones of Blues News bring word that Natural Selection 2 developers Unknown Worlds have released their ‘Decoder’ IDE – their Integrated Development Environment, or Thing Wot They Used To Program The Game – for free, taking the exciting decision to make it open source as well. The team created Decoder in 2007 using the programming language Lua, and until now they’ve been licensing it out to other developers, using the money to fund the company. Now that NS2 is out, Unknown Worlds have decided to not only remove the licensing fee but to open its innards to the public, with the intention of making it “the best IDE out there!”
