According to the wiki, the PC version of Dungeon Defenders comes with the "gameplay code and source" for UDK, for the purposes of modding.

However, it's not listed in the usual place ("Tools" in Steam), and I can't find any other info online. Where is the source code?

You can find the optional DLC where the source code is located here, or you can find it under the DLC tab in the store page.

Now you can find the source code located at \Steam\steamapps\common\dungeon defenders\Development\Src\

\Development\Src\: This contains all the gameplay source code for Dungeon Defenders (in UnrealScript, which you can learn through the Unreal Developer Network). It's located here for Mod coding & reference purposes in particular.

awesome, it'll be good to finally see some of the formulas in the game. – l I Nov 4 '11 at 17:57
Cool, a small note about how to install it (for googlers) and I will give you the checkmark – BlueRaja - Danny Pflughoeft Nov 11 '11 at 18:14

Looks like it was delayed. For those who don't need the latest and greatest, there's a link on the UDK Page.

That source is older than dust, and completely useless for modding. – BlueRaja - Danny Pflughoeft Nov 9 '11 at 4:37

It's under steam's tools section now!

Er, where? I don't see it. – BlueRaja - Danny Pflughoeft Oct 25 '11 at 23:14
title? link? anything to back this up? – Maslow Oct 27 '11 at 4:19
Not seeing it either. Are you posting this in case it becomes correct at some point, or what? – a cat Oct 31 '11 at 12:33
