Proving Grounds is another of the oldest arenas from Quake III that has made its way over to Quake Live with suprisingly few changes to the original recipe: a medium sized symmetrical layout consisting of one large room over several floors with a pillar and some jump pads surrounded by a series of corridors that lead off to an imposing triptych sitting opposite a short bridge over a fog pit to a teleporter. There are very few changes in its Quake Live incarnation, so please refer to the original Q3A review for more information.
