Conjoined: Eight Minutes Of Binding Of Isaac: Rebirth Co-Op

Alice already delivered information about how co-op will work in Binding of Isaac: Rebirth, but if you weren’t paying attention at the back of the class, perhaps you’d like to see the mode in action. Designer Edmund McMillen has played the game for seconds shy of eight minutes, showing off some of the new co-op challenges, items and abilities that extend the Nicalis’-developed game beyond “remake” territory into the well-established “remake-sorta-sequel-sorta-standalone-expansion-sorta” territory.

Anyway. Watch the video below. It’s got about a million tears in it.

Because tears are bullets in Binding of Isaac.

The way co-op works is that the additional player steals a single heart from player one upon entering the game. That means that player one has two instead of three hitpoints and their co-op partner – who in this instance is a floating troll-baby who uncontrollably poops occasional bombs – has just one. Should your baby die, they’ll respawn as a different kind of baby, but only if player one has a heart to spare for them. As you’ll see in the video above.

The original Binding of Isaac was built in Flash as a quick project by Edmund McMillen and Florian Himsl, after the release of McMillen’s Super Meat Boy (which was made with Tommy Refenes as part of Team Meat). Rebirth is a full re-code of that original game, to solve a bunch of problems native to Flash and, while at it, add a bunch of new stuff. It’s due out later this year.

McMillen continues to work as part of Team Meat of course, on the on-hold Mew-Genics and on the just-announced A Voyeur for September, which is maybe a game and maybe an anagram of Super Meat Boy Forever and therefore a viral marketing campaign. Who knows, videogames? Who knows.

    Edmund tweeted today that Guppy passed away. Glory to feline hero!

      Rest in peace you legendary video game feline. We will always remember you wherever your next to useless items drop in the game. :)

        Always that slim chance that you’ll nab three of them and become a flying, fly spawning kitty though.

    That was a shit video. Literally and figuratively.

    Here I am, one of the biggest proponents of 8 or 16 bit SNES style graphics, but I can’t endorse its application in this game. It looked a lot better before. The retro style is great, but shouldn’t necessarily be applied universally across the board. Not a deal breaker or anything, just a little peeve.

    • Baines says:

      It is kind of weird how the graphics seem to look worse with each video.

      The jagged look just doesn’t match the character art. It doesn’t look like good pixel art. It doesn’t have the detail or the care. It looks like Flash/vector art that has been traced/redone in semi-large pixels.

      And the lighting is too much “Hey, we have fancy lighting” without any concern for how it affects the game.

      • Nenjin says:

        So it’s not just me. I don’t mind the lighting, but I swear everything looks jaggier and jaggier with each iteration. I don’t know if it’s the resolution they picked, or that they’re not using Antialiasing, but I just played about 4 hours of BoI last night and compared it to the video….and the graphics look noticeably worse in Rebirth.

    • Richeh says:

      I was thinking it looked really good. Slick animation, and a nice feel to the atmospheric effect. I’m on board for it.

    • SuddenSight says:

      I look forward to a long eternity of endless discussions on which BoI looks better. Every post on BoI must consider whether the pixel aesthetic is good, even though it was also considered on every previous post and just about every point has been made and it is too late for the developers to change their minds anyway. Discussions must be rehashed!

        Yeah, otherwise they won’t be sorted properly if they change.
