I don't like the idea of a machine that vaporizes floors repeatedly if emagged, unless you mean that it just remove the tile to leave plating behind (which doesn't really sound antaggy). You let it loose in a maintenance tunnel to breach the room. It then enters a department, breaches that department. Then it enters a primary hall. Suddenly, there's breaches spreading everywhere, will probably kill a lot of people, and I don't think that makes for very good RP.
