I think your review was spot on, I also really enjoyed the influences from the AvP movie and the fact that each level has Predator Jungle bits as well as the Alien metal environments.
I love the Alien environments but found the previous games didn't use the Predator enough when it came to level design.
I do think its strange that they took out the 2 Alien influenced levels for DLC, instead of one of each.
The ranked matches definately need work and they need to release the DLC maps already so I can play the ones I got with the Collecters Edition ^^
'Maybe Rebbelion will make a patch to fix that litle problem… for PC version'
Wanted to comment on this as it seems a lot of PC gamers think that we don't get fixes\patches\updates on consoles - so glad we do
Lets hope they start rolling something out to fix the few flaws that everyone seems to agree on (stealth kill distance, smart disk etc)
