As a rule the biggest issue with Radroaches up until now has been trying to hit the little bugger outside of VATS. But we may have a bigger issue: they appear to be learning, as shown by this alpha-roach using a waste paper bin as protection while attacking gamer Matt Gribble (opens in new tab).
I'm always impressed when game systems are robust enough to make this sort of thing work - collision detection and physics working together in hideous harmony to create the next evolution of Fallout monster. And, as the discoverer always names his find, say hello to the 'iron roach'.
