OS2U-1

The OS2U-1 is the fifth plane in Merge Plane and is purple. It earns without upgrades 85 coins per Golden boxes spawn those usually around planes 10-16. Ranks 15,000-10,000 tend to find this plane very helpful, and ranks 10,000-5,000 tend to find this plane fairly helpful. However, in the top 2000 it’s usually a bad idea to buy this plane. If your highest plane is 11-15, you’ll find that this plane has a big boost when it comes to time warps. Overall: buy this plane in the beginning stages of the game but say goodbye to OS2U-1s once you get to plane 20. second.
