Being my first map, I can't claim it's bug-free or even all that hot in terms of action, but since I'm continuing to develop more maps I thought I'd toss it out and see if anyone can offer any constructive criticism. I have taken pains to eliminate every bug I could find. The only remaining one I'm aware of at this point is a bad (purple) cubemap somewhere in the red base, but that doesn't bother me too much.
Here's a front view of the red base:
And a plan view of the whole play area:
The open area with lots of high vantages is sniper-friendly, but there are underwater routes and ground cover to compensate. There are lots of ways into and out of each base, but I think I've balanced it fairly well for difficulty of both offense and defense.
