Sometimes, a scene in a movie can be so complicated that you need a detailed plan. And in the case of Thor: Ragnarok, that detailed plan came in the form of an homage to top-down, 8-bit video games.

[Warning: The above video contains major spoilers for Thor: Ragnarok.]

In order to plan out the twists and turns of the film’s climactic final battle on the Rainbow Bridge, the pre-visualization teams on Thor: Ragnarok made this short video. Sprites of Heimdall, Thor, Valkyrie, Hulk, Korg and Loki battle it out against the forces of Hela in this clip, available only with the digital release of the film, which comes out on Feb. 20. Polygon is able to offer you this sneak peek at it, courtesy of Disney.

Overall, it’s easy to see how the production needed something like this to sort itself out: A lot of stuff happens in that fight. Secret plans, surprise returns, changes in allegiance — and all on a battlefield that’s only two-hero sprites wide!

Thor: Ragnarok will be available on Blu-ray and 4K Ultra HD on March 6. It will arrive digitally in HD and 4K Ultra HD and on Movies Anywhere two week earlier, on Feb. 20.
