I like the idea for your map. It looks and feels like a sewer setting. Here are my thoughts. I was a bit confused by the energy shields in top center bridge, they dont fit into the 'sewage' setting to me. I like how the incoming sewage river pushes you towards bottom center but am confused how the crates in there dont move as well. In bottom center the decals used look a bit off. This map is great for team slayer and ffa, however i think it is too open for CTF and SH. With the only access to up to being stairs and lift, there was not as much vertical game play as i would have liked being that its so open. Maybe solve this with a 2way teleporter from bottom to top? FFA was by far the best, i would consider moving your CTF/SH positions to change up the game flow. Great job all in all. I will be interested in trying out future downloads!
