How to Create a Zerg Invasion map with the StarCraft 2 Editor
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 make a Starship Troopers (film, not book) style map where a group of Terrans have to defend a remote base from hordes of Zerg. It was created pre-patch 13, so it may be a little out-of-date, but most of it still works and this map looks really killer, so try it out!
