Ok heres my 2 cents
Epic i think worked quite hard on this yet there are still many bugs features missing. However so far i think the Pros outweigh the cons.
Anyway i know you're mostly vCTF like we are, but here are my opinions on the maps.
vCTF:
Rails - Excellent map, so many possibilities for capping and its got a nice flow
Stranded - Blue SHOULD win this
Suspense Necris - Utter sh** worst map i ever saw
WAR:
Confrontation - Excellent map, great fun to play, good visuals, and no core n00bing with some bugs as there is no way to get to the core, its at the end of a long tunnel you have to shoot with manta/raptor or when you go up a jumpad you have a brief second to get some shots on it
Hostile - Nice eerily themed map, can tell its suppose to be based on Na Pali for those that played Unreal I
Cold Harbor - Great map, only way to kill core is with a node
Downtown Necris - Better than the susp necris conversion, but still, sh**
CTF:
Haven't played any of the new maps in CTF, so i can't comment on their game play
DM:
Koos Barge - By far my favourite DM map, great for 1v1 and is the UT3 predescessor to Koos Galleon (UT99)
OceanRelic - Great map, my second favourite DM map :D
Turbine - Great remake of the classic map from UT99
Morbias - Not exactly new ... and is just rocket arena (was released in the bonus pack, last year)
DarkMatch - Great gameplay, appart from in DM you can see name tags so its not really "Dark" enough xD
EdenInc - Nice designed map, enjoyed it
Greed: First of all this is a great gametype, combine team deathmatch with CTF and could say gives a Bombing Run feel from UT2k4
Stranded - Red should win this, easier to get down the hill to score skulls
Rails - Great fun, ballanced match
Susp Necrs - Not even going to say
NanoBlack - Great fun to play in Greed
Lost Cause - Great fun to play in greed
Morbid - Boring
Face - Good fun, too much sniping, though
Shaft - Nice map, easy to get lost at first
Searchlight - Overall i say its ok, but not my favourite of them all...
Anyway overall i think its a great expansion, but they need to release a new patch ASAP to fix the server issues and some Clientside issues too.
