This guide will teach you how to calibrate the Asteroid Defense System (ADS) Cannons in Chapter 4 of the Dead Space remake!
This guide is for the Dead Space Remake, released in 2023!
When Isaac reaches the Bridge of the USG Ishimura, he learns that the Asteroid Defense Cannons are malfunctioning due to a lack of power. After going around the Bridge to reallocate power to the ADS Cannons, things only get worse as they have lost their calibration data. Isaac volunteers to go to the outer hull of the ship to recalibrate them manually.
This experience is quite different from the original Dead Space in 2008. In the original, you would operate an ADS Cannon and manually fire at the asteroids as if it was a turret.
This level was notoriously hard for console players in particular due to the speed that the asteroids came in at the USG Ishimura. This part of Dead Space has been revamped entirely in the remake!
Get familiar with your surroundings
After you’ve redistributed power to the ADS Cannons throughout the Bridge, you’re going to have to get out into space to calibrate them yourself. Before you do be sure to take time to save at the Save Station near the air lock.
Head out the air lock and make your way outside. A message stating the current hull integrity of the ship is at 86%. If this hits 0%, then you and the USG Ishimura will be ripped to shreds. Fortunately, you have a good chunk of time to calibrate the ADS Cannons before this happens.
The control consoles for the ADS Cannons can easily be found by looking for the yellow lights beneath the consoles. The first ADS Cannon console will be to your left.
For each ADS Cannon console, there will be Oxygen Refill Tanks on the opposite side. To the right of the first ADS Cannon you’ll find oxygen, left of the second ADS Cannon, and right of the third ADS Cannon. Be sure to use these if you’re running low on oxygen.
How to calibrate the ADS Cannons
Your next step is to fly using Zero-G to get ton the first ADS Cannon. A blue panel will ask you to Override the cannon, use the Activate button to do so.
The ADS Cannon will now follow your targeting reticule’s movements while in Aiming Mode. Use Aiming Mode to point the cannon’s targeting reticules at an asteroid. You’ll need to use your Activate Button instead of your Fire Button to fire the cannon. Firing the cannon is the “Call a Strike” action in this event.
You’ll have to destroy 5 asteroids this way before the ADS Cannon is calibrated and begins firing on asteroids automatically. Once this is done, move onto the next ADS Cannon further up.
As you go further up, two Lurkers will attack you from behind. You can dispatch them or tell them it can wait a bit and that you’re in the middle of some calibrations.
After you’ve calibrated the second ADS Cannon, fly over to the third and final cannon. Don’t forget to refill on oxygen so you don’t suffocate. Once you finished calibrating the third ADS Cannon, you can take some time to breathe as now the asteroids will no longer be a problem!
Find Officer White’s RIG and get inside
While you’re here, fly a bit past the third ADS Cannon to find the remains of some crew members. Look for the glowing purple light like in the image below.
Going here will allow you to find Officer White’s RIG. This is needed to complete the “You Are Not Authorized” side mission, take the time to pick it up as that quest is well worth completing.
Make your way back inside so you can proceed with your quest on the USG Ishimura, those necromorphs aren’t going to dismember themselves! And with that, this concludes this guide. This new version of the ADS Cannon event in Dead Space is miles better and more interactive than the original version. Good luck on your quest to save the USG Ishimura!
