The Rocket Chair's exact function is unknown, as there is no discrenible reason why someone would use the Rocket Chair as a mode of transportation unless they were in Isaac's exact situation.The HALO Jump takes place in this chapter.The USG Ishimura can actually be seen from the Zero-G area outside the Solar Array.The first Nest is fought in this chapter.Dodging large debris Isaac reaches the surface and proceeds to meet up with Ellie and Stross. Fearing that they will be cut off from Gov Sec Isaac sits down in the Rocket Chair and starts a head down dive towards the Sprawl's surface. Now with the power online he goes back to the Rocket Chair Room only to be informed by Ellie that a large group of Necromorphs is destroying everything in their path. Exiting the room he starts to align the panels and also fights off a Nest. He then proceeds to the Solar Panels where he is confronted by yet another Nicole Hallucination in the Rocket Chair Room. But with the computers off now he has to align the Panels manually. After passing the booby trap filled rooms he reaches the Mainframe of ANTI and successfully deactivates it. Finally reaching the Solar Array he navigates the Facility guarded by ANTI. Boarding the lift he starts going up only to be attacked by multiple Tripods which he successfully fights off. Reaching the lift Isaac finds out that it is floating at the bottom of the elevator shaft so he flies down and raises it up with some Rocket Canisters. Isaac moves from the Transport Hub in the CEC Facility towards a lift that will take him to the Solar Array. If the necros get a little too close for comfort, use TK to slow them down and be sure to immediately take out any screamers that appear, before they get too close.Isaac ventures up to the Solar Array in a bid to activate life support and power in order to take a train to Government Sector. Pop the panels but one and when you have killed 16 necromorphs, then go for the last panel to finish things up. I used the flame thrower to protect myself and the pulse rifle to pop the panels when necessary. In this sequence,Gabe will need to fend off wave after wave of necromorphs while needing to shoot the 4 panels around the door to let it open. If you did not heed the spoiler warning at the top, then prepare for the end sequence of the game. Kill 16 or more enemies in the final last stand combat sequence. Now that you have the second Peng statue in Dead Space 2…what the hell is PENG!? Remember the The Peng statue will be on the table here against the far wall. Deal with it and follow the corridor around to the right and you will come to a locked vent shaft. Enter the large room with large columns and steam in the air and make your way to the far end where a Pregnant will come around the corner. After you reach the large necromorph in the lab coat and see a half opened door in the hallway, head through the door opposite the elevator entrance. In the second chapter, you will come to a large hospital area. Now that you have the second Peng statue in Dead Space 2…what the hell is PENG!? I simply backed myself into a corner and let everything come to me as I obliterated it from a relatively safe distance.Once the countdown reaches zero and you open the door, the achievement/trophy will pop for you. Basically just after the Grinder Room, you will come to a room with locked security doors and you need to fend of the attacking Necros until the countdown reaches zero. This achievement is story related so it’s impossible to miss unless you move off of the platform. Defend the quarry platform until the door unlocks.
