The Resistance spray-painted the lambda symbol, the Half-Life logo, next to hidden stashes of supplies all over the game. There are 45 of them, and finding every one unlocks the Lambda Locator achievement. Valve's numbers put it among the game's rarest: only 2.6% of Steam players had earned it by 2018.
How to find it
The first one is unmissable: the lambda next to the fake Breen's Private Reserve vending machine that hides Kleiner's lab in A Red Letter Day. After that, keep an eye on walls, rooftops and canal pipes for the painted symbol.
