Don't get me wrong, I like a challenge But the teleporting guys need some work.
I mean, where's the fun in running around a level for an hour trying to find the last guy, let alone the last guy who upon being found, then buggers off to the other side of the map. This was an annoyance with the OG, and these guys make that annoyance worse lol!
I would suggest that they have a much more limited range, and upon teleporting successfully they should make a noise where an on screen indicator gives you an idea of where they've gone to.
