The Twitch E3 2017 Pre Pre Show had Aaron Webber on as a guest to preview what Sonic Forces and Sonic Mania content will be playable at SEGA’s booth. The segment, which can be seen in full here, showed off the previously unseen Sonic Mania Green Hill Zone Act 2 boss which turned out to be Dr. Eggman’s giant end boss mech from Sonic the Hedgehog 2. Meanwhile, Sonic Forces showed off the Classic Sonic Green Hill Zone boss which turned out to be modern Eggman swinging a giant saw blade before bringing out the Egg Dragoon, previously seen in Sonic Unleashed and Sonic Generations.
Also showcased was a modern Sonic Sonic Forces stage. Worth noting, the Sonic Forces world map classifies the stages as “Sonic Stage”, “Classic Stage” and “Avatar Stage”. Also, during the classic Sonic boss battle in Sonic Forces, modern Eggman refers to classic Sonic as being from another dimension. Uh-oh, is Iizuka messing with canon again?
