WPCentral posted Killer Instinct 2 Classic review ? the vintage fighter returns with online play on Xbox One A quote from the article:

In 1994, the original Killer Instinct took arcades by storm. The next year a downgraded but respectable Super Nintendo port followed, along with a GameBoy version. The home games helped maintain enthusiasm until Killer Instinct 2 arrived in arcades in 1996. The Nintendo 64 would see a mildly stripped-down port called Killer Instinct Gold that year. The true arcade version of Killer Instinct 2 has never been available on home consoles? Until now. Like Killer Instinct Classic before it, Killer Instinct 2 Classic comes bundled with the purchase of Killer Instinct 2 Ultra Edition on Xbox One. The $39.99 bundle gets you eight characters in the new Killer Instinct, plus Killer Instinct 2 as a standalone game. Killer Instinct 2 Classic even gets online play, making it a more viable alternative to Killer Instinct Season 2. Read on for gameplay details, hands-on video, and exclusive screenshots!
