This map has huge sized rooms with items distributed over a very wide range, flattened textures and Georgia Guidestones. I don't think it should. What I did like about this level is the following: the water tunnels, overall design of tanks, hellish area shown in the preview screenshot, grenade trap in the narrower room and the fact that the map has bot support. Almost everything else needs some very, but very significant improvement, in my opinion, and that's in terms of visuals, gameplay and context.

There are some textures from Quake, Quake II and Doom on this level, but I don't think that just the textures alone recreate the atmosphere of any of these classic games, so I am really confused by the fact they are present on the level in a bare form, without anything else giving a feeling of (a) certain conversion(s).

With a different scale the fact that the map features all the weapons (except maybe the Grappling Hook, which, by the way, would come really in handy here), major power-ups and a lot of items will make much, much more sense.
