A repository for other workshop items that can be used to simulate the powers of certain aliens. For example, a fireball addon for heatblast, a pack with crystal shards that look similar to Diamondhead's, etc. I'm making this because I had an addon with gemstones that were similar in design to Diamondhead's, but I can't find it again. I could have sworn they were part of the TF2 invasion prop pack.
