Resin Detector (Campaign Only)

NOTE: Start game with addons from Chapter 2: The Quarantine Zone
(it may not work if you start from the beginning, this is a known issue with any campaign addon)

Make Alyx's multi-tool even more useful by turning it into a resin detector! To use it, just select the multi-tool: while in your hand, it will passively beep every two seconds if it detects nearby resin. The beep will indicate the direction and proximity of the resin: the louder it is, the closer it is!

This simple feature transforms resin-hunting from a blind, haphazard chore, to a fun, cerebral detective game. The beeping is just a small hint: you'll still have to be observant, explore every corner and rack your brain in order to find all resin. You'll be surprised at some of the cheeky hiding spots that you might never have discovered otherwise!

Before relying on this addon, I recommend you complete at least one full playthrough where you try to find as much resin as you can on your own. Then, activate Resin Detector, start a new game from the Quarantine Zone, and find out what you missed!

In my test playthrough, I was able to detect all resin in the 100% Resin Guide except for one which you can visually see but is too far away to trigger a beep. There is also one resin that doesn't spawn until you complete a certain task, so the detector won't catch it until it spawns. Finally, this addon moves one known broken resin that was previously completely hidden but still triggering a beep; it is now easily accessible.

So you should now be able to get a maximum of...
298 + 1 bugged + 1 broken, now fixed! + 4 bonus
= 304 total resin (only 270 needed for all upgrades)
