Is a "black hole mania" for the D2 possible? I always liked that scenario.
The one I posted up there spawns a new black hole roughly once a minute, just hope you're not sitting where it chooses to spawn.
At the moment it only generates up to 8 of them (in addition to the "normal" terrain in the mission) but it could be boosted to 20 with a minor tweak.
It uses the pseudo-random technique we were talking about in the other thread, so it
should be stable in drafting situations.
Other than that it's a pretty normal enemy space patrol.
