Here is the quickest and easiest way to do it on hard. Step one: open the door. (Stand by it) Step two: snipe the gate keeper. Step three: open the left portal. Step four: two people go in with rockets, if done right you will instantly kill the gate keeper. It is best if the person not picking up the relic shoots two or three rockets ASAP and leaves to let the other guy finish it in one or two rockets as he is running for the relic. You only get marked when it is dead. Step five: the second you grab the relic ONE person needs to go to the middle to defend. -the guy in the middle needs to go right to the back BEHIND the Minotaur spawn point. You will not be bothered by anything else. They will spawn slowly with their backs too you. (I use AE to drain the shield, then praetorians foil to finish them. Use your grenades always, and rockets as an 'oh shit') easy. Step five continued: The other five players should now be opening the right (and shooting) as the relic flys over and right in. One guy joins him. Step six: the relic holder shoots his super at the keeper as the other guy uses rockets. Instant death. Relic holder cleanses and clears mobs as other guy grabs the second relic. (Remember to cleanse him again first relic holder) Step seven: all outside, middle stairs is covered still so one relic guy on left one one right, AND one other guy stands behind them with rockets, of course. This leaves the last guy not doing much so it's all good if he is dead, else he can just aid the killing. This method is so quick, so easy, my regular team has it down to perfection. We couldn't run it faster if there were no mobs. Seriously. (4 Ghorn rockets from a 30 equals dead gate keeper, just two each) Hope this was clear and helpful :)
