I've started replaying Wanton Destruction to get the remaining secrets I sure missed. Once I made it to the second level, I noticed the first enemies you get to meet don't seem to display a bit of discomfort towards your presence, even if you try to slice some dead, they won't fire back and others won't react. Since I'm unable to recreate the problem, this is probably a harmlessly random bug , anyhow, here's the 7zipped save for the curious.

By the way, are these black-coated guys replacing ninjas supposed to lose their aiming skills when you crouch in front of them or that's jut by design?.
