    At first I thought 'wow, that old dinosaur fighting game I played as a kid!'
    Then I was disappointed because it said '10 year anniversary' and the game is much older than that.
    Then I clicked the link and realised they'd released a modern version I didn't even know about 10 years ago, and now it's free!

      Primal Rage?

      • +6

        Oh what the heck? You're right, I was actually thinking of Primal Rage. Not sure what happened with my brain there, because I genuinely associated "Killer Instinct" with the dinosaur fighting game. I also played the original Killer Instinct too, so great nostalgia hit either way.

        I can tell by your username that you're an old school gamer too!

        • Haha i did too

        One must Fall 2097 was an amazing game. It was everything Rise of the Robots was hyped to be, but wasnt.

        If anyone wants to try out One Must Fall 2097 for their first time, or revisit it for nostalgia, its available as a freeware download, and fully playable using DOSBox. Here are some relevant links:

    what great memories, this game had 10 tokens for the next players in the queue at timezone.

  • This is one of those games I never understood.

    But… Free is free

    • Neither do I, but I manage to do a lot of the combos just by mashing buttons. Fun game.

    C-c-c-c-combo breaker!

    Bought it but never played it. Now I have a free upgrade to the Anniversary edition. Win win.

    • every time someone confesses they bought a game they never played, jv gets extra 5 minutes of OzBargain Premium for free

      little to say, jv is a premium member for life. make it legendary @jv!

  • I have added links to the deal post description for the Microsoft / Xbox Store's versions of the Killer Instinct base games, one for Microsoft Windows 10 PCs, and one for Xbox One / Xbox Series X|S consoles. These are also now free-to-play and can be added to your Microsoft Store / Xbox account's library.

    • +2

      Is there a benefit adding it to your account now its free to play? You can play/add it anytime right?

  • I cant get the store page to load in my steam app.

    I can search for the game & see it & I can wishlist the game - but when I try to load the games store page (in the steam app) I get a black screen

    • Same problem earlier, actually it has been a while. But it loaded for me now. Maybe a steam issue because other sections of the app was working. I even turned off adblock

      • thanks for the info. I tried again & now it shows up - thankyou

  • +1

    Thanks. Got it on both!

  • I clicked in and already had the base game but Steam still displays the Anniversary Edition for purchase so I don't think I've been automatically upgraded for whatever reason

    • According to the official blog post, if you're an owner of the pre-Anniversary Edition version of the game on your Steam account, you should be entitled to a free upgrade to the Anniversary Edition.

      You may want to reach out to the developers' support channel(s) on the Ultra Combo website and/or Steam store, and raise a ticket

      • +1

        The store says I have the game in my steam library and still has the option to buy the anniversary edition. But when I go in game, I have access to all the characters.

    • @SpainKing as per Mugsy's comment, did you try launching the game itself, and not just rely on what the Steam store / Steam launcher's library says? Perhaps all of the Anniversary Edition content have been downloaded and are accessible after all, by directly launching the game?

      • +1

        I didn't, so if Mugsy's comment is right I probably do have it. Laptop's low on space so I didn't want to download it to check

  • +1

    Love this game!

    Cannot believe MS hasn't used the devs to make a MS IP fighting game.

    Would be incredible!

    And fyi the game was already 4K on Xbox One X but now for Series S and X it also has a 4K UI and some effects which were a lower res are apparently also 4K.

    I'll play my SNES version of the real classic.

    Loved this on the arcade machines, supposedly there was going to be an n64 release to be like for like of the arcade version but couldn't find one down under.

    Orchid and glacier were the all time favs

    • +1

      My understanding is that the original port of KI to N64 ended up being the SNES version because of the fiasco between Nintendo dropping Sony's CD tech (which later became the Playstation) and the delays that came from it.

      Conversely, I'm more sad that KI2's slated SNES conversion didn't come to light. As cool as the arcade version's graphics are, there was always a charm the SNES version (and 16-bit consoles in general) had that I would have loved to have seen the sequel on there too. As great as Street Fighter 2 and Mortal Kombat are, when I think of the definitive fighting game for the SNES, I think KI… it was home grown and it was glorious!

      The newer 3D reboot isn't bad though. Pity it doesn't have an MK styled story mode. KI has so much back story it would work.

      • +1

        The lore stands out in a lot of ways.

        There was another arcade fighter at the same time where is was a middles ages type fighting game. You could pick from a number of characters such as executioner with axe and mask as well as a knight just to name a couple. There were many more and also had an execution or fatality as well.

        Great game.

        • +2

          I'm assuming you're not referring to Soul Edge or Soul Calibur as that name is pretty widely own and the theme isn't middle ages.

          Was it Mace: The Dark Age?


          EDIT: Just re-read your post… definitely not the Soul games since they have no fatality… unless one considers a ring out a fatality.

          • +1

            @Mugsy: Mace: The Dark Age would have been my guess as well, to Kiro's comment about a 2D fighting game with a Middle Ages-setting, on arcade machines …

            … if Kiro had said it was a console game, I was thinking it could possibly be WeaponLord on SNES and Mega Drive/Genesis ?

          • +1

            @Mugsy: That's it, wish they had it on console….. Even mame. Great fun.

    For those who don't read before they download 30gb of data and are slightly disappointed with themselves…:

    One of the best fighting games I've ever played!

    I have updated the deal post's description > References bullet points to include:
