Needs a Goin' Solo+ mode, where others wont go attack the same enemy, even if there aren't any others around. Also a Stay+ so that they stay in a certain area, but never leave. If enemies come one at a time, all your guys end up in a single crowd.
I think that this is based around strange matter, because whatever particles it toutches, it turns that into strange matter as well. Accept, instead of eating one object at a time and taking about 15 minutes to eat earth, it would take about .2 seconds.
