Not much detail, but it's a TDM so it's somewhat excusable.
Arena looks small, more like a shoot out if anything. Seems a tad small for a team deathmatch though. Surrounding hallways dont fit in very well; why would there be a hallway in the shape of a square? Doesn't serve much purpose IRL. (again excusable; but could have been done better.)
5/10 nothing much to make this TDM stand out from average DM's or 30 minute builds.
