Depends. If you're in my time zone (GMT+1 I think) then I'd say that about 7pm would be a good time to try. On the other hand, most of my playing time is random, I'm not really sure what time it is.
Try in the later evening, maybe.

Hehe, at last a funny 40K joke!
That was good, I'll try to make one of my own...

I've re-read your text (for the fourth time :p) and like it more and more. I can't point out where exactly a word or two would be added, but basically sometimes a word could use an adjective more.
What I'm trying to say is that the changes I would have made would be insignificant^^

Pros:What is there to say? It's really good!
Cons:I think that in some places you missed a little potential for description.
Improvements:As I say, describe things SLIGHTLY more, and it'll be perfect.
Comments:Was this your first go at writing? 'cause if so, you've got a talent!

For objectives, maybe sources of heat (although I don't know how well fire renders in exterminatus, and I wouldn't have any idea how to model a plasma well), or long lost relics hidden under the surface...

Hey, maybe I could try an angry marine skin, once I've got some time!

I dont know how to make objectives change owners more than once, but here's how it could be played:
Marines: Start in spawn. 2 directions: Left and upper right. Left goes to objective 1, right divides in two: one that goes to objective 2, one that climbs even further, to a direct path to the nid spawn area.
Nids: Start in spawn. 3 directions: Left (objective 2), right (objective 1), and middle/up (towards the marine spawn area).

You could add other waypoints, camp areas, tunnels (like a tunnel from objective 1 to 2), traps (you know, explosions, fire, or just simply damage. Just got a idea: consider that it's so cold, to traverse certain places you take some damage per second, but those passages are a shorter way between objectives), and other things that come across your mind. I'd consider a bridge over a river, so frozen you die in it within seconds.

W00T! Yeah, the Ultramarine book was really long, but really, really good!
Anybody ever read "Titanicus"? I think that's the title...

Well first map out the general layout, very roughly, with the dev textures. Don't even add the props yet. Once that's done, add your objectives to capture. Stuff like buttons to press or areas that a marine must manage to stand on are good. Then roughen the walls, the floors, and start the cave (Did I mention? Make the cave a square before really making it.). After that, since your map's gonna be snowy, I propose two ideas;
a) A white map is really easy to skin, 'cause if the skin is stretched too much and creates a pattern, it's less noticeable than, say, grass or rock.
b) Add some fog! That could become an interesting problem for the marines, not seeing the nids before it's almost too late. That could also fix the marine><nid team issue in the beginning of the round.

Question: Are the Smurfs capturing the points, or the nids? Usually Ultrasmurfs are, so making the nids capture could make things interesting, provided that lictors can't take positions while being invisible. It would make things more organised too, making the nids organise a general rush to get past the heavy bolters and so on guarding the objectives.

I don't think that Terminators or other races will be added. But for the apothecaries: not such a bad idea at all, in fact! A narthecium to heal wounds would be cool (could have an ammo system that is resupplied from the ragdolls, with gene seed and all, but that would be difficult). On the other hand, the nids are left without a healing unit. Maybe add a fast assault unit like a gargoyle to counter the apothecary? Or give the Zoanthrope a "healing aura"?

Oooooh, shiny! Very nice work indeed! That's a definite download.

Not bad at all, and not silly either! Just a tad short, but keep posting!
PS: Yeah, it seems to not have any errors concerning the 40K universe.

Servers...Yesterday, no. And I'd love to set one up. I've got source dedicated server tool. I just don't knoàw how to set it up for ex.

Have any of you been pirating my computer or my brain? I was building a "surprise" first map that looks almost identical to that bunker map! My own map, however, instead of your G, has a river. Oh, and the nids can break through the roof of the bunker as well as from the side. But thanks so much for that diagram!

Nice! Sounds like a real tabletop mission!
