Ecco II: Sentinels of the Universe was a planned entry in the Ecco the Dolphin series of video games. The game was developed as a follow-up to Ecco the Dolphin: Defender of the Future (2000) on the Sega Dreamcast, but was cancelled upon the discontinuation of the Dreamcast platform in 2001. Content and prototype builds from development have slowly been made public in subsequent years.
