Power Blade on the NES. You are a Schwarzenegger-in-his-prime-like character in the future fighting the robotic underlings of an AI gone rogue. It has only 7 levels or so, but it has a nice gameplay to it, and the music was composed by Kinuyo Yamashita, who also did the Castlevania music. Needless to say, the soundtrack is top notch.
Oh, you’re not gonna wait for Online that long. It’s gonna be their main focus for sure.
