SC2REPLAY is a Real Time Strategy (RTS) file extension called StarCraft II: Wings of Liberty. SC2REPLAY are files used to save gameplay replays. To play such a file, the user must have the game installed. This is due to the fact that the SC2REPLAY file contains only player actions defined in a specific order, and the replay itself is visualized by the game. The advantage of this solution is the very small size of SC2REPLAY files.

StarCraft II: Wings of Liberty is a game produced and published by Blizzard Entertainment.
