As for a different kind of tractor beam, would it be possible to have a special type of brick that, when laid, prizes everyone in the near vicinity (including the user) an engines shutdown?
Sounds interesting I do think it would be really cool if the disruptor was just black though. People will wonder "wth? what killed me?" It might encourage actually using it, if not just for fun The phaser won't be possible to change though. I'll see what I can do once I get some free time.
