Players have added Star Wars ships, the fictional sport Quidditch from Harry Potter, and a live avalanche to Halo 5: Guardians with the game’s Forge mode. Now, one creative player has recreated the zero-gravity Battle Room from Ender’s Game, and you can have actual battles just like the ones from the book and movie.

Reddit user Aurelien-131 is the minigame’s creator, and he showed what the mode looks like in a GIF he posted to the gaming subreddit. The Battle Room in Ender’s Game hosts battles between two “armies,” where they can shoot to freeze each other and open their enemy’s gate to get in. Aurelien couldn’t recreate this perfectly in Halo 5, so they put a twist on it.

Players start with plasma pistols that have infinite ammo. For the gates, they put strongholds that work in a similar way to the movie–in Ender’s Game, five people need to get through the gate to end the battle, while a Halo stronghold gets captured faster as more people stand within it. Capturing the stronghold wins the match, but you can also kill all enemy players if you want to take a more violent approach. Whoever takes three rounds first wins the match.

Aurelien offered some advice to people who want to play his Ender’s Game-like mode.

“Since playing Halo with no gravity is probably not a common occurrence for most of you, I’ll add this tip: Going up is as simple as jumping, but going back down can be tricky,” they said. “Ground pounding is the obvious choice, but for a slower and more controlled descent you can simply zoom in so that your stabilizers activate, which will make you fall when you let go. As a last resort you can also boost to the nearest wall and the downward slope of the sphere will guide you down.”

They added that “8v8 is ideal” for this mode, though 4v4 should be fine. You can read their entire post here.

It was recently announced that Halo 5’s Forge tools would make their way to the PC later this year. A PC version of Halo 5 was not announced, though people will be able to make Forge maps on PC and publish them for use on Xbox One.
