Valve have brought out a Left 4 Dead 2 toolset to enable modders to create maps for other gamers.
Don’t worry though, if you’re not up for the idea of creating your own maps there’s still something for you; the add-on support package will allow gamers to play on custom maps made by others, including those from the first title.
If you’re into map-making you’ll need to download the Authoring Tools. These are just like those from the first game but with a few extra bits. Gamemode Logic is one new feature, which will intelligently self-edit maps to adapt them to the mode being played. Another new feature is Director Logic, this detects particularly capable teams and makes the game a little harder.
There’s full support for Scavenge mode and an illustrated manual to help you start modding.
The Left 4 Dead blog has all the information on where to get it all.
