Eliminate Manta's movement

[Ion Mage]

Also unrelated to this threads topic but how about replacing the singularity with a nuclear reactor that can be fueled with all the different kinds of radioactive minerals mining digs up. That could make for a nice change of pace for Engineering and maby even have it so that someone has to check on the reactor from time to time to prevent it from melting down or someone who's up to no good messing with it.

IIRC that was the original plan, Manta was going to have a nuke reactor, but the map got pushed out before the nuke reactor was completely coded in, and was substituted by the singularity in the interim.  And then development of Manta stopped because Reasons.
