On my YouTube channel I've created a gameplay walkthrough video covering chapter 4 of this game.
Chapter 4: Obliteration Imminent - This video covers Isaac arriving on the bridge to meet with Hammond. After saying goodbye to Chen the two come up with a plan to get the Orbital Defense System cannons back online to protect the Ishimura from asteroids that are peppering the ship in the debris field. To do this our mission objectives are to redirect the power from administration systems to the ADS cannons by rewiring 3 junction boxes throughout the area. Once this is done we have to manually calibrate the cannons so they target the asteroids. At the end of the chapter we receive a call from Nichole that will draw us back to Medical next.
In this video we find the Contact Beam weapon, schematics for the Intermediate Engineer Rig, and die 1 time trying to get the ODS cannons calibrated (Total Death Count: 4).
If you found the video helpful, please consider giving a like and/or subscribe. This is a small channel on YouTube and any support is greatly appreciated.
At 12 minutes into the video the Brute Force achievement is unlocked for killing a brute. This is the first brute you'll encounter, and it is pretty much required to kill it to proceed. I've created a 36 second short covering the 2 best ways to kill brutes.
