It's always bugged me that when an enemy new kid's last phone is destroyed, and they fall to the ground they disappear, along with their name on the health bar.
In my opinion, both the nk sprite and the player name should remain on screen until the end.
In a related note, what would be really cool is some sort of "gibbing" system where if the final blow to nk is over a certain threshold they blow up in a gory explosion. There is a similar system in place in the original Doom on PC.
Thanks!
