I'm having a terrible time getting past level viii of this First Order Challenge, but I'm just trying to get 1 more point to get to 85 points. So I'm trying to accomplish "Attempt to apply thermal detonators 40 times." Jawas, Zam, and Greedo are mediocre, but I thought I could at least use them on the middle levels. However, I either kill everyone off too quickly at lower levels, or I draw on middle/higher levels (because KRU refuses to die for all 15 minutes and keeps recovering health). I'm unsure what combinations to use. Anyone have any combinations that have worked for them? I need one darned point!
