The game mode (or mod) would overlap with the existing gameplay types by restricting available weapons to the base environmental weapons only (concrete and wooden poles, cars, shields, alien weapons). No loadout weapons could be used.
Each game-mode could be implemented within the larger category of Tools At Hand (the name I'm using to express the concept). TDM with the above weapons only sounds fun, as do other game play modes.
Any thoughts? Like/Dislike?
