    Pretty simple and basically the same as all the others. Step one: obtain the sensor. You cannot miss the sequence. Once you have it, you’ll have to find 9 Spartan cores scattered about on your tac map represented by a small triangle icon.

    To help find Spartan cores, activate nearby FOBs. This will show nearby points of interest. Also listen for the beeping noise they make toast

    Originally for my first playthrough it was bugged. My 2nd easy run through of the game to gather the remaining collectibles it finally popped. Hopefully their latest patch corrects this issue.

    T0NY HAYABUSASo I can't even select the threat sensor from the upgrades yet I have it unlocked and have used it before. All that I can highlight and upgrade is the Graplleshot.

    ReimKamm071481@T0NY HAYABUSA: Try deselecting Settings > Accessibility > Linear navigation mode. That solved the problem for me.
