The Ark (level): Difference between revisions

The Chief and the ODSTs meet up with a group of Marines whose Pelican was shot down.  The Marines inform the Chief that there's a good landing zone for the ''Forward Unto Dawn'' nearby.  After retaking the Pelican crash site, John-117 and his allies commandeer an assortment of vehicles and drive off to secure the LZ. Along the way, the Chief discovers a large Forerunner wall built between the cliffs. The entrance to the wall is guarded by [[Sentinels]] which attack the Covenant but leave the humans alone. Johnson arrives in a Pelican and informs Commander Keyes that Hocus has found a structure located on the other side of the wall. Keyes deduces it's a Cartographer which they can use to locate the Prophet of Truth.   

The Chief arrives at the ''Forward Unto Dawn's'' intended landing zone and defeats the Covenant forces occupying it including a pair of Anti-Air Wraiths.  With the landing zone secure, the ''Forward Unto Dawn'' enters the installation's atmosphere and deploys reinforcements, including Scorpion tanks. Keyes orders the Master Chief to take the convoy through the wall and locate the Cartographer. John-117 takes a tank and leads the armored convoy against a large force of Covenant vehicles and infantry. [[343 Guilty Spark]] accompanies the humans and opens the entrance to the wall, allowing John-117 to enter on foot. Inside, he activates a light bridge, allowing the UNSC convoy to pass through the wall.

Upon reaching the other side, the UNSC encounters another large force of Covenant vehicles, including a Scarab, guarding the structure containing the Cartographer. After a prolonged battle, the Chief and his allies prevail.  At the same time, Shipmaster 'Vadum reports that Truth's fleet has been defeated. The Chief heads up to the top of the structure, where he teams up with Thel 'Vadam and a pair of Marines. 343 Guilty Spark opens the doors, allowing the Chief and his allies to enter.  The group fights their way into the lower depths of the building and finally locate the Cartographer. Upon accessing the Cartographer, John-117 discovers that they are outside the Milky Way galaxy, and that this installation is, in fact, [[Installation 00|the real Ark]].  Guilty Spark locates the Prophet of Truth, who has activated a protective barrier around himself. Spark then discovers [[Installation 08|something else]], but before he can reveal what it is, a hostile Phantom arrives. Johnson contacts the Chief and warns him that additional Covenant forces are heading their way. Thel 'Vadam hijacks a Banshee and engages the Phantom, while the Chief and the Marines head to the lower level to meet up with their evac. After defeating more Covenant troops, including a Jiralhanae Chieftain, the Chief is picked up by Johnson's Pelican. As they leave, a massive force of Sentinels are seen departing on an unknown priority mission. Though Guilty Spark wants to focus on finding Cortana's solution to the Flood, Commander Keyes states that they must stop the Prophet of Truth first.
