Starcraft 2, like it's predecessor before it, has a very robust level editor that allows you, the DIY modder, to create nearly any scenario within the bounds of the Starcraft 2 engine that you could imagine. We have compiled videos on how to do all sorts of fun things with it, from making RPG's and Tower Defense games to just making you dream Starcraft 2 level. This video will teach you how to work with items and loot in your custom levels. You'll learn how to create items, create ancillary items like bags to use the items with, divide them into item classes, make enemies drop items, and finally, how to sell the items. This is all must-know stuff if you want to make any sort of RPG-like mod, so watch!
This was made on patch 13 of the SC2 Beta editor.
