Roses vs Violets Achievement in Halo: The Master Chief Collection

The best place to get this achievement is on Episode 1, Chapter 5. After the first major firefight, you will reach the top of the Forerunner bridge-like structure that leads to the first objective. At this point, follow the outer wall that lines this area until you find a small break in the wall that you can look through. If you jump on the ledge and look down into the molten rocks, you will find a small chest sitting on the rocks. Go ahead and shoot this chest with any weapon in order to unlock the achievement. If you require a visual aid in obtaining this achievement, make sure to check out the video guide below.
