I think Aliens need some kind of visible model. Nothing large or obtrusive, a simple claw type swing is all. I believe this would help between the transition between human and aliens.
Also, which I feel is even more important, markings on walls when hit by aliens. You hear the swing sound but it would be nice to see a puff of smoke particles come off walls when you hit them. Seems very miniscule but this would be helpful for me to get a better feel of the different classes and where their swing hits exactly.
dretch teeth
marauder leg... wth
I forgot to add. Dretch and Granger would not need anything but everything else, all Im asking for is a swinging leg or claw.
Would that do more damage?
blah blah, use search function, blah blah, allready suggested and done, will be implemented in next version, blah blah
