From Destinypedia, the Destiny wiki
It is highly recommended to bring a Void-based weapon as there are a large number of very aggressive Minotaurs in the later parts of the Strike. Killing them quickly will be the key to staying alive.
Objective: Kill the three Servitors
Players begin in the Ishtar Commons, with a group of Vex and Fallen fighting each other. These can be ignored; walk right past the two Hobgoblins further into the academy right into the N/GEN Branch. This area is the first Darkness Zone. The fireteam's objective is to kill three Servitors, which are found in different areas in the room and guarded by multiple Fallen. Note: two of the Servitors spawn simultaneously, with Captains guarding them along with the usual Fallen.
It is recommended to kill the Fallen quickly if the Servitors are still alive, as Servitors will heal any nearby Fallen. After all three are killed, players must climb up the staircase, where they will meet multiple Vandals armed with Shock Swords. Defeat them and continue into the next area.
Dig Site 4
The first Vex enemies will start to appear, with a handful of more Fallen. Enemy composition is fairly light until a large clearing with Vex ruins where a few Hobgoblins and two Minotaurs can be found. Proceed further into the ruins to enter the caves where The Nexus is found. A small swarm of Goblins will appear, but can be dispatched quickly enough.
Boss: Sekrion, Nexus Mind
At the end of the caves is a large room with a very steep drop. Drop down (taking care to cushion your fall) and kill the many Minotaurs patrolling the room (it's recommended to engage only one at a time). If a player chooses not to drop down, be aware of a Minotaur that spawns every so often.
Killing all the Minotaurs will bring down Sekrion; it will hover in the center of the room with a shield rotating around it. Because its projectile attack is quite powerful, players need to find refuge around the outskirts of the room, where there is sufficient cover. Every so often Vex reinforcements will teleport in; it is important to be aware of them, as they can include Minotaurs and Hobgoblins and easily kill any players already being harassed by Sekrion's attacks.
Sekrion's weak point is its yellow glowing eye, which is only exposed if it is facing the player and its shield isn't blocking it. This can be difficult for players as it requires both timing and willingness to be exposed to its fire. Coordinating good fire angles so that the head can be hit from other angles will help bring down Sekrion more quickly.
