Halo Infinite is here, and it's magical. It's also synonymous with the end of 2021: a little bit of a mess, but a lot of fun. It also features a lot of quality content, something that you couldn't really say for a lot of other games that have come out this year. Honesty, Halo Infinite will probably be our game of the year, but it will depend on what all of you EarlyGamers vote for. Anyway, there are lots of achievements in Halo Infinite, but what about the secret ones?

Yes, that's right, not all Halo Infinite Achievements are viewable, and in fact, there are a ton of secret achievements in the game. Isn't that just exciting? These achievements are the true sign of a Halo god, as it is impossible to fight for them unless you have read, well, this article. What are these secret achievements in Halo Infinite, and why should you vie for them? What does vie mean? What is going on? Maybe we should just go and eat a pizza, that sounds a lot easier. Oh, wait, let's get on with the article...

How many Secret Achievements are there in Halo Infinite?

There are 18 Secret Achievements in Halo Infinite. They might not be listed, but they certainly exist, and most of them are related to the game's campaign and story components. Many of Halo Infinite's Secret Achievements are a little bit underwhelming, considering that they are for completing super basic tasks such as "Defeat[ing] the Banished warlord Tremonius". Many of these are pretty bloody pointless, but some of them are kind of cool.

Probably not as some of the games that are coming out in January, though...
