I am looking forward to the Alien/Xenomorph very much, more so than all the other KP2 characters. NRS have captured 'it', extremely well, kudos to them. From the looks of things, the Alien looks like it'll deal a lot of chip damage. That 'assist' in the other variation (lets just call it 'Queen', even though Queen Aliens are huge and have four arms.) is the icing on the cake for me.
With that huge tail, I'm thinking this character will be a force to be reckoned with, with great footsies, chip, cancels and from what you guys have said, command grabs also. I think it'll be top tier.
Hopefully it has some sort of projectile or a special to close the distance really quickly, similar to Reptiles bf2.
