Atari and Obsidian are set to release the Neverwinter Nights 2 toolset a month ahead of the game's release in October.
That's providing you pre-order it now from "selected retailers" - the offer's active now in both the US and Europe.
As well as advance access to the toolset, which allows you to create your own game modules (and, well, virtually your own entire games), you'll also receive "The Merchant's Friend", which is "a special feature enabling players to obtain powerful items crafted especially for each of the 12 classes".
The toolset's set to be made available online in five days' time to those with a pre-order unlock code, and you can keep an eye on the countdown at Atari.com.
