I saw this on another server and absolutely loved it. Its a 1-use traitor weapon. When fired, a loud noice will be heard and +- 2 second later a rocket with headcrabs will land on wherever you pointed it. Great for taking out groups. Only works on maps with an open sky like a certain minecraft map with a lighthouse.
