Ram them with a vehicle, collapse the ceiling on them, hit it with a sledgehammer a lot of times, get a hulk to smash it apart.[/quote]
All of those can work (I wonder if you can jackhammer them?), but it will destroy any breakables inside… but then, I think the only thing that drops in them that is “breakable” is mutagen and purified, which are much more available elsewhere.
Critters first:
-I find zombie scientists to be the easiest and a good place to start. They actually drop some really awesome ones VERY rarely, but they butcher several useful ones reliably.
-Broken cyborgs butcher to power CBM. REALLY easy.
-Technicians butcher to some useful things and are pretty easy.
-Biooperators and shocker brutes butcher to REALLY nice stuff.
-Shockers butcher to some decent starter stuff.
-Survivor zombies drop some occasionally, but I haven’t had one butcher a CBM in a long time, if ever.
-Survivors sometimes butcher to some - usually power, sometimes power Mk II, I think I’ve gotten a few other things, very rarely.
-Soldiers very rarely drop some pretty good ones, but I’ve never seen one butcher to a CBM.
Now places:
-Science labs - the “utility” style rooms sometimes have some VERY nice ones just lying around (in the crates or on the racks). The CBM storage rooms are a great place for the basics. And, of course, there are lots of scientists, some broken cyborgs, and the occasional biooperator. I’ve even seen a few in the barracks armory before. Also, there are some books that give you the recipe for several useful CBMs, at least one of two of which ONLY spawn here. In experimental, you better BLOODY WELL HURRY if you want the special stuff at the bottom, as the secubots blow themselves up on the dissectors and destroy it all if the loot isn’t sealed up.
-Electronics stores - pretty rare in the normal shop, fairly common to get a few one of the rare configurations, sealed in glass or locked in the display case.
-military crash sites - sometimes, these are AWESOME. Seriously, when you get a CBM-themed one, it can be just WOW.
-Ant hill - fusion blaster arms (no idea why) and metabolic CBM. Maybe one more… I forget.
-military bunker - one of the storage room choices is a CBM stash. Rare, but VERY nice.
-Sewage plant - odd, but I’ve occasionally seen some really good stuff here. I also found the elf mutagen book here once, oddly eough.
-mines - racks near the top, the corpses you find lying around.
-military outpost - I don’t recall finding any here just lying around, but this is decent source of bio-operators (seen as many as 5 at one outpost).
-Libraries, bookstores, mansions, and schools (for the library) - not that there are any CBMs here, but you can get books with recipes to MAKE several CBMs, including a few that are fairly rare to find otherwise (aero-evaporator, for instance).
I think that about covers it. Did I miss anything?
