Part 1 : Not so alone in the dark Right after dropping into the dark below, you'll all be marked by a curse called "Weight of the Darkness" that slows you down, prevents double jumping and even running when it reaches the X10 multiplier. That multiplier grows when you're in the dark In this area, you can get a chest right from the start. There are many threads out there on the matter. I'll add links here later. So, what you need to do here is pretty simple in theory. You have to navigate that dark maze from one light pillar to the next. Considering that the curse will stack everytime you go in the dark, you will need to wait a bit at those pillars from time to time. We stopped a bit longer every 2/3 pillars Be carefull, those lights will extinguish after a time and you'll be in trouble they EXPLODE So, best way to do it is to have a leader that decides what the group does at each pillar and announces which direction is the next pillar AND the holes in the ground. Basically, you follow his steps. No need to rush like a mad man, if you take the time to lower your curse, you can be pretty cautious and you'll get to the next in time. Use shotguns, heavy machine gun and the vex to go through the enemies. Shoot the ones in front of you and watch out for those close to the holes as they can push you in.... ALWAYS stop at the next pillar when a knight spawns among the numerous crappy mobs and kill him to avoid being chased by them as well. In the end, you'll reach a rather large circle that you need to stay in. It will materialize a bridge over time. Split your group in 2 and watch right and left in the direction you came from. Drop all you have on ogres and knights. Titan bubbles with weapons of light in the back of the is pretty usefull. Titan with their area of effect super are also nice if too many mobs get to the plate. You definitely need to focus on the rushing knights so you dont get overwhelmed. The ogres have pretty heavy DPS so they need to go down as well. Having 2/3 guardians sticking with ice breakers and 2/3 others using mob crowd control weapon (HMG, Fatebringer with explosive rounds) should be pretty efficient. You only have to hold off the enemies for a definite amount of time (3 to 4 minutes give or take) before you'll see a notice about the "path being open" meaning the bridge behind you has materialized. Then cross the bridge, kill\dodge the ogre on the other side (Spawn seems random, he may not be there). Rush toward the light. Get loot ! DONE.     Part 2 : Cross the bridge So, here you are on higher ground over a room that features : a big hole, a fire ghost bridge thingy, a central plate and 2 beacons on each side. You can't see it yet, but on the other side of the bridge, you'll find the same central plate and beacons. So how does it work ? Basically, the central plate and the beacons act as a trigger to materialize the bridge and you only need to activate it from one side. Things to know about this trigger : The first step is to have someone on the central plate AS SOON as this plate is activated, you need to have someone under the beacon thing at all time to open the bridge.If you dont have someone there, it will go oracle on you and wipe your team.In case of emergency, leaving the central plate will cancel the curse from an unoccupied beacon. This seems easy so far right. Except you can only cross the bridge with Crota's Sword. So, whenever you activate the central plate and beacons, a nasty swordbearer will spawn. Destroy him and take the dropped sword. Watch out as he can rush right\left\center randomly. When someone holds the sword, he can cross the bridge (with ppl still on central plate and beacons). When getting to the other side, there will be a blueish knight. YOU CAN ONLY KILL IT WITH THE SWORD. One will spawn every time a sword bearer is killed which means that everyone that crosses the bridge will have to kill a blueish knight with the sword. It is not mandatory but it's a lot easier to not have them around. If you end up missing one, know that wont come at you if you stay under the beacons. Might come in handy. (Confirmed by huntermthws) Luckily, there's a way to kill those knights without too much trouble as ill explain later. The trickiest one will be the first as no one can distract him. So be carefull. When the knight is dead, the guy who crossed the bridge will have to wait the others and will enjoy battling with yellow tough knights. Those need to be killed so you dont end up with a ton of them. When the second guardian comes with the sword, the first guardian will see the Blue Knight arrive. That guardian must absolutely aggro the knight and run around in front of the bridge WITHOUT activating the central plate (or not for long). This will allow the second guardian to take on the knight by surprise and spamkill him with R1\RB. Another trick someone shared with me is using flashbangs to stun the knight and kill him easy. But the "catch me if you can trick" works well. I dont mention the cheese thing to make them fall... Do this for the first three guardians. When three have crossed, they will now do the opening of the bridge. One on the central plate, the others on the side. The three remaining guardians on the original side gathers just in front of the bridge AND DONT ACTIVATE THE PLATE. Their sole purpose is to focus on the sword bearer. When he crosses the bridge, his role will be to back up one beacon on the side (left gets massive heat) AND help take down the swordbearer on the opposite side (ice breaking looooove). Same thing goes for the 2 remaining guardians. When the last one arrives and kills his blue knight, the entire party must abandon the plate and beacons and run for cover to the right side (bridge in back). You all got through, now your main concern is to survive. Go right then and destroy the wizard and ogre. They're the one that seems to trigger the end of that phase (needs more testing to be sure). Have one of you watching your asses as the doors behind you will spawn small mobs who can still be real painfull. Also, Try and keep an eye on the beacons as one activated without us knowing why and almost wiped us (thank you Sun God). No idea what happend really but keep your eyes open. But overall, once you all crossed the bridge, you should be ok and enjoy the loot. ** A chest is available at the very end of the corridor that follows. It's time sensitive but be carefull on the way as there are shriekers and a lot of mobs. Chest is behind a door right behind the hole at the end. Part 3 : Wizards and Shriekers As a reminder, this phase is about killing the master wizard (Main Bitch in the drawing) that hangs out with a glowing crystal in a weird energy prison we can't enter in. And obviously, as soon as you get in the room, you have a limited time (between 2:30 / 3 minutes. That invisible countdown seems to start as soon as you shoot an enemy or a friend receives damage) to kill her otherwise she'll sing you a nice lullaby that will have you sleeping forever. Her singing also starts as soon as you destroy the 2 shriekers so the sooner you can destroy them, the longer you'll have to fire at her (Need more testing but i think it triggers it as well). Now, the mecanic of this phase is that you need to get access to the main wizard (cant remember her\his name) and then spam it like if it was a damn pissed off gorgon (which she kinda is). To do that you have to break the 2 shriekers located on each side of the crystal room. But of course those shriekers can only be taken down after their dedicated wizards are killed. So, now with the strategy. The strategy First, you need to split in 2 groups. Try and make them as logical as possible. Having one titan each side with WOL is a very good thing if possible. Basically, each group will take cover in a position (those platforms up there) on each side of the room. Allowing for a quick and safe destruction of the wizard on both side and the mobs that come with her. So let's go : 1) To avoid any complications, kill the first 2 knights to avoid being OSed when running to your safe spots. PRO HINT : take 20 seconds before going to get ammo back in your ice breakers then focus fire. You'll drop the 2 knights in seconds. 2) When done, each group runs directly to its side and takes the stairs. Dont mind mobs or knights on the ground. When you reach the top of the stairs, reverse and jump in those high vantage point rooms. 3) Kill the ice rocket knights and clean a bit on both side => ATTENTION, the group that goes left tends to aggro some more mobs that will stay below them, right group has to shoot those mobs whenever possible. 4) While cleaning is happening, one guy on each side has to go lurk a wizard out. Just go halfway in the room and go back to the high vantage point. Watch out for the knights that will spawn along the wizards. 5) SPAM ENEMIES !!! Use WOL, rockets (but keep some). Ice breaker is your best friend to be honest. So is Vision of confluence. They usually stack right outside the room where you went to lurk the wizard and are sitting ducks there. Only the wizard can hurt, the sword guys are just standing there. 6) When the wizards on both sides are dead, clean the remaining knights. Then move closer to the shrieker room on both side. 7) Have a First group destroy its shrieker and immediately go back and join join the other group. Nevermind the mobs around the first shrieker, fire 1/2 rockets and a few bullets and go. 8) Have 4 of you simply kill
