Using Alien Swarm and the built in tools it shipped with it’s possible to load the DotA 2 particle files into the Source engine particle editor. You can find a tutorial on how to load DotA 2′s PCFs into the Alien Swarm tools at the bottom of this post.
Screenshots
I have attached some screenshots below to show off the particle editor and some of the unreleased heroes` particles (click to enlarge).
