RF Online, which stands for "Rising Force", is a free-to-play sci-fi MMORPG originally developed by South Korean developer CCR. A Philippine server was published under Level Up! from 2005 until 2013. A SEA server was published by PlayPark from 2017 until 2024. There are currently no official RF Online servers being published as of 2024.

The RF Online IP was transferred to South Korean mobile game developer Netmarble Corp. in 2020 when it acquired CCR. PlayPark's RF Online is the last official server to operate, as Netmarble decided to terminate all servers globally for the game in 2023 and 2024.
