i have said this over and over again, about the dodging thing, i love the idea, but i hate how you people have set it up, change the buttons around instead of hitting shift (my sprint button) and hitting a ( left stride) to dodge that way, you should make it like in unreal tournament 2000-08 hit a,s,d,w twice causing you to dodge in that direction, i think if you do this, it will improve the dodging ability by far, also you'll be able to dance around aliens still. Without relaying on back pedaling and dodging into strange directions.
thanks for reading (if you want any more ideas i could make some more up)
