Throughout play you will come across dead soldiers that have a glowing red item. If you loot this then you will gain 1 point to be used on an upgrade. Each upgrade has a set cost. One of the cheap categories is Area-scanning Technology. This category has 3 upgrades, it costs a total of 6 points to fully upgrade it. I went for this category as it shows secrets on you map and has a pinging affect when close to them. This helps you find more upgrades so you can find upgrades easier.
Upon completing any of the categories, you will unlock this trophy.
