Halo: The Master Chief Collection was released in 2019 as a celebration of all things Halo. The bundle provides you with access to six mainline games from the franchise in one neat package, all with one common launcher. The best part is, you get to choose which games to install and save precious hard drive space in the process.
Halo: The Master Chief Collection gives a modern-day polish to old-school titles like Halo CE, with features such as support for 4K 60 FPS and ultra-wide monitors enabled out of the box. Graphics get an overhaul, too, and if the new visuals don't hit the mark, you can switch to the original Xbox 360 graphics with the press of a button on some games.
All six games also support seamless multiplayer with classic and new maps. But this comes with an undesirable side effect. An Xbox Live account is mandatory, even to play single-player campaigns. Its system requirements aren't particularly demanding, and Halo: The Master Chief Collection can run on any PC built in the past ten years. Strictly speaking, it isn't Steam Deck verified, but that's largely due to software quirks.
You can get Halo: The Master Chief Collection on Steam for just $9.99 or equivalent amount in your local currency. That comes down to less than $2 per game, which is an absolute steal given the amount of content you can get out of it.
