Cache 1/45 ( d1_trainstation_05): Upon meeting Alyx Vance, she will bring Gordon towards Kleiner's Lab.

The following is a list of all the Lambda caches that can be found by the player in Half-Life 2 they count towards the Lambda Locator Achievement. The lambda is also seen in graffiti and propaganda posters across City 17.Ī huge Lambda logo can also be found on the rocket hatch and a smaller one on the button used to launch it at White Forest. The Lambda logo can be seen on certain vehicles, such as the orange van that Dog throws to the Citadel in Episode One although any van-type vehicle, regardless of color, has a Lambda logo under the right tail-light. They are also used to identify Resistance-friendly Combine weapons such as Hopper Mines and Sentry Turrets, seen by the spray-paint on them.

Resistance fighters also wear the symbol on their arm bands. They would spray-paint it near supply caches, and resistance bases and safehouses such as White Forest, Black Mesa East, and Kleiner's Lab. Gordon's Lambda logo on his suit and the work of the Lambda Complex became something of a legendary trademark symbol for the Resistance against the Combine, referring to the acts of Gordon Freeman during the Black Mesa Incident, and turning the symbol into an informal logo for the Resistance, reminding of the real world Anarchist symbol, of similar purpose. In the original Half-Life, Gordon Freeman's trademark HEV Suit was marked with a Lambda Logo on the chest, as were other HEV Suits, due to their use in the Lambda Complex - a section of Black Mesa dedicated to teleportation research - identifiable by the Lambda logo at its entrance.
