This map actually looks pretty good in my opinion, I like the middle structure/ the one made out of fence walls. However, the gameplay might be lacking with 4 shotguns, as other people have said.
Although they only have 1 clip, that's still waaaay too many. Especially for a map of its size >_>. I barely even use power weapons on my map. Killswitch v.1 (Soon to be posted) has only a sniper with no reloads, a rocket with no reloads, and a mauler. And that's a large foundry map! Either way, besides the gameplay, the map looks very nice. I especially like the explosions in the center.
