The Lambda Cache can be found on the left side under where the flooring has been torn up. After climbing up, head into the boarded-up building immediately on your right. Lambda Cache #2: While escaping the Combine, you will have to jump onto a moving train to reach a ladder on the other side. Head back the way you came, & Barney will show up to drop an old friend off for you. After being teleported further into City 17, you will get stuck behind a door barred by wood. Achievement #5 – Trusty Hardware: Get the Crowbar.
