Alright... so some quick details before I can write up anything else. I got to play three of the new maps and they are:
1. WAR-Cold Harbour - this is the one that we've got the concept art for (check that feature). You can catch glimpses of it in the trailer - it's pretty easy to spot. There's not a lot to this one as it's basically a V shaped node/core layout with two un-linked Air nodes flanking the point of the V. All in all, not too bad, but it's a bit smaller than I had imagined. It works though.
2. DM-KoosBarge - if you look at the trailer, you can catch it real quickly - it's the barge (duh!). It's more or less inspired by UT's DM-KoosGalleon. If you remember that one, then you've imagined the remake. It's still small, still pretty tight, and utterly simple. Imagine an open topped barge with fighting taking place in the small hold and on the surface of the barge. One nice touch is that the barge rocks all around with the waves.
3. VCTF-Rails - if you like RocketTurrets then you'll LOVE this map. If not then you might not. Each team has one and a rail that runs the length of the map - yes all the way to the enemy base. It is a destroyed city type setting (not unlike any of the others in UT3) and it's medium sized though very simple. The open courtyard of each has a base structure and a few short doorways/pathways in the nearby buildings. The map is cut in half by a canal. There are really only two road routes that cross the center, so there's definitely a congestion point.
