This pack contains a bunch of models and skins of things that may or may not go BOOM! Because what is a video game without exploding?
These aren't scripted to explode yet. You'll need to do that in your game. Also, the textures are all 1024x1024 - grossly unoptimized. If you need smaller images, just resize them. Some people like those high-res images.
All the materials are default Unity bumped specular. Textures are diffuse (with specular in the alpha channel) and normal maps.
