How to unlock the Cups - 50% achievement in TETRA's Escape - Definitive Guide
Each level has 3 stars to be collected. After collecting all 3, a cup you can also collect will appear. If you collect all stars and cups when progressing though the worlds, you will unlock this trophy when completing world 4.
For a collectible guide please see World 1. Do note that the video guide does not cover all the stars and cups for world 5 and above. So if you are missing collectibles after world 4 follow the text guide instead.
In every level three are 3 stars to collect. Collecting the third one will make a trophy ("cup") appear at a set spot in the level. You then have to collect the trophy and then finish the level. These typically force you to complete the level in a certain way so you not only can get all three stars but can then also go get the trophy depending on where it's placed.
The "World 6" achievement solution has a video guide that includes getting the trophy in all levels through the end of World 4, which is enough for this achievement.
