You know the map, the wide open one with all the houses on the sides? The one where joel had to snipe to keep his friends alive? Yeah, that one. Shorten it a bit in the middle, open up the houses more, and string about some random cover in the middleground.
Another map like lakeside, but summery, and still quite interesting.
Someone said Hospital. That would be cool. I'd like a multi-storied building. How about a Department Store with lots of manicans (spelling?) You'd always think you saw someone lol. Fighting in a Walmart would be funny lol. Or a Mall!
I like dynamic maps, but the whole snow/sand storm effect doesn't really impress me. When those 2 effects come, I usually can't wait for it to go away. Dynamics in the form of the map crumbling and paths being altered would be cool.
