Halo Infinite: Secret Achievement Greased Lightning Explained

Greased Lightning is a secret achievement in Halo Infinite that can be a little tricky to unlock. Here's a quick explainer to get you there.

Halo Infinite's multiplayer surprise released on November 15th alongside Xbox's 20th Anniversary Stream. While the multiplayer is still officially in beta, it's free-to-play, fully featured, and carries progression into the final release. The Spartan Academy tutorial actually includes some story not seen in the Halo Infinite campaign, so it's worth it to complete even if you know how to play the game. Using the route outlined by My Good Username, here’s how to unlock the Greased Lightning Achievement.

You have to make sure you jump from just the right spot to just the right corner. Got it on like my 10th run lol

[angeloperri]

You can actually close the door and run it the first time timed if you interact with the console

Much appreciated. This took me four tries because it was my first time on the tutorial. The ledge is so random

It's much easier to just jump off the box to the left of that ledge at the start

You can just push that button you don’t have to do the course before starting the timer.

Avery J. Johnson Academy of Military Science. Aw.

[tebo]

This is hard because of bad movement mechanic (grabbing the ledge next to rail being all too random)
