Completing the Groundbreaking quest in Arc Raiders can be a little bit tricky. The first part, where you have to locate a locked room in Pilgrim's Peak, isn't so hard, but then you have to track down a building based on a drawing on a white board, and that's, understandably, a bit tougher.
Similar to the Armored Transports quest, you also require a Blue Gate Communication Tower Key to even see the board in that first room, and that can potentially cause issues if you lose it before opening the door. Thankfully, there's a way to get a spare key, which I explain in the guide below, and it's a fairly busy loot room, so you'll often just find it open either way.
