I don't know if this is a bug, but there is a minor annoyance when using the minigun on imps. If one is leaping at you as you wind up your minigun, he'll do a weird "double dodge" where he dodges the minigun in mid-leap. It's hard to describe and I have no way to record footage of it, but it does happen and it can be rather annoying, especially against groups of imps.
Also, Mark, why did you never tell me the chainsaw was so good for fighting imps
. Just kidding, but chainsawing imps in half has become my new pastime
