Ok, took longer than I expected (got into Fallout 3), but here's v2 of Grave Digger. I didn't change the shape at all, but the inside is much different. Uh, it still looks like a shovel.
This is small, just like my other map. It took a lot more work than my last map did, though. Basically, there is a large(ish) base at the head of the shovel, and a smaller one at the handle. It has a room in the middle and two hallways on each side. Wow. All i really did was take White Forrest and took the top off and put it somewhere else. Oh well.
As for gametypes, I recommend slayer. I set up some KoTH and CTF stuff, but slayer variants are best. I don't have a gametype made for it, but I can make one if anyone wants one. Just give me a suggestion.

I replaced the dumpsters with stairs. Much happier.

Put fence walls where the walls were. Looks a lot better.

Took out hallways and added lots of cover.
Well, that's pretty much it. Still don't have a gemetype. Hope you like it.
