Now, now, I know what you think. But I don't mean cursed items that wield themselves to your hands (although it's hell outthere on Phobos). What I mean, that med-packs could contain THC, so for some turns you wouldn't actually be able to shoot anyone (peace brother!).
Plasma rifles that tend to overheat, and that leads to a disaster - explosion of the plasma rifle (although plasma rifles are still high-tech, so you get a warning and 10 seconds to drop that weapon or throw away from you).
Advanced weapons that actually aren't that advanced at all. You are ready to put your 3 damage mods into the advanced combat shotgun, and after putting the second one.. WTF, I cannot put more mods to that gun.
And the most important, Thermonuclear bomb. You are almost dead, you plant the bomb and... damn it! The detonator's gone! That's why I always take some spare bombs with me...
How to check if an item is "cursed"?
Well, if you're an Ironman or Tough as Nails, you quickly can tell what's inside a medpack.
Having finesse, it's harder for you to destroy a plasma rifle.
Whizkid? You quickly can tell how moddable a weapon is.
As for thermies, you have to be a one big son of a bitch to tell wheter the thermie will explode.
