Most pain and death sounds for humans and aliens are either very quite or just don't have *that* feeling - for example the rant death sounds don't have that good old feeling where the rant got shot to death and it's yell of pain really showed the tyrant is dead.
Alienevolve.wav is vey nice tho, I like it, just could be a half-second longer.
All granger sounds are just plainly retarded... literally...
Basi taunt sound is too short. Grab sound is very nice tho. Jump sound is quite acceptable too. Pain and death sounds are as mentioned above.
Dragoon jump sound is more like a pain sound or something like that, however as it is also the pounce sound it's fine. The pain sounds are somewhat good. Taunt sound also gives that alien growl effect, which is good.
Dretch death and pain sounds are suprisingly very good. Taunt sound is also very good. Jump sound is also very good. I have a feeling dretch has the best sound pack from all the aliens.
Marauder death sounds sound something like a headcrab from Half-life and Alien from Aliens vs Predator series... not very good - it doesn't fit the marauder. Jump sound is fine. Pain and taunt sounds are same as death sounds.
Didn't check any footstep sound - I'm quite much done for todays reviewing.
