As one of the best, if not the best, of all the BR maps out there, Twin Tombs is nothing short of amazing. It features several routes to either goal, 2 amps, 2 super armors, and a well thought out item placement. Simply put, this map does everything right.
Critique:
The best part of the map is that at any given point you can pick another route to take the ball, and confuse the hell out of the other team. However the map is so small and frenetic thst the ruse never lasts long. Plus, the availability of strong weapons and power ups makes for constant carnage. This is the best BR map out there.
