Arriving on the 11th anniversary, Halo 3 ODST is coming back to our screens.

We first experienced this pleasure of a game in 2009 on Xbox 360.

It will be fully optimised to run as smoothly as possible on modern PCs.


The fan favourite 'Fireflight' mode will also be available in-game!

Take on hordes of enemies which progressively get harder to defeat.

Release Date

Halo 3 ODST will be releasing on PC on the 22nd of September.

“Halo 3: ODST will officially arrive on PC as part of the Master Chief Collection, on September 22,” 343 Industries tweeted from the Halo Twitter account. “Suit up, strap in, and prepare to return to New Mombassa.”

For those wondering what time you can get your mitts on the game, it's all set to drop on Steam at 6:00pm BST.

Download Size

There isn't a clear download size but we can estimate based off of other titles in the series.

Many other Halos have been within the 10-20 GB range.



Currently, we don't know whether Halo 3 ODST will be available to preload.

Previously Halo games have not had the preload feature so it's unlikely this game will be any different.
