Hello Sodaraptor!
When I saw your new video on YouTube announcing 5.3.3 I was very pleasantly surprised, particularly to see the new enemy (the 'green mutant'). Awesome stuff as always.
This spurred me on to try out a new challenge of running the gauntlet without picking up or using any weapon whatsoever, except the final boss which you have to kill, and in order to do this, I had to make use of baiting the enemies into killing each other (yes yes, I know someone is going to say "but you have five kills at the end" - but trying to define 'no trash mob kills by my own hand' is a little much for a YT video title! :) )
Is enemy vs. enemy a new feature as part of this update? I've never seen that before! Due to the sheer number of enemies now, this is legitimately the only way to get through groups in tight corridors if you're going full-on pacifist, and if two enemies are standing side by side in front of you, they'll hit each other rather than hit you, as it seems each strike can only impact one target. Absolutely not a complaint, just a curious observation!!
Also even without a weapon, Hawk still has a 'targeting reticule' in front of him - again, wasn't sure if that was intentional or not.
