Guardians of the Galaxy Cosmic Rewind is a reverse launch coaster currently under construction in the World Discovery (Future World) area of EPCOT.
This attraction is re-using the former Ellen's Energy Adventure building as a queue area and will load/unload passengers in an omnicoaster ride vehicle and reverse launch them into a new building built beside the Play! Pavilion.
Although there is no official opening date, it is widely expected to open during EPCOT's 40 anniversary (late 2021 - 2022).
