Overall the map is about 85% complete, in the last couple of days I've been working on going over certain areas detailing them progressively in stages. They still need populating with a few more props, but here's a little peep:
We also had a little playtest today (once we had stopped having much lulz with spawning npc's and jeeps); me, jimbo, kraid and kobayashi. Which very much helped me see what areas were scarce of weapons and ammunition, as well as areas with it that were a lot of the time ignored (the ammo and weapon under the staircase got overlooked by most people, so I'll be moving that to a nearby open area where a weapon is needed).
I can safely say that this map is geared towards the higher player counts.. much in the same way that Runway is, by my estimate you want a minimum of 8 players, or 10 for a team game for this map not to feel too gigantic, it can easily handle twice that.
Anyway thanks to everyone that's given feedback so far, criticisms are always welcome and are helping to shape this map to its full potential.
Please ignore the floating crate in the 2nd image.
