Short answer
Halo: Campaign Evolved has a Steam page with Standard and Premium purchase options. Steam buyers should check the 100 GB storage requirement, Windows 11 requirement and whether they want early access through Premium.
Steam edition differences
| Option | Who it fits | Key note |
|---|---|---|
| Standard on Steam | PC players who only want the campaign. | Lowest listed Steam route for buying the game. |
| Premium on Steam | PC players who want early access and digital extras. | Includes Premium benefits rather than the physical collector package. |
| Steam Collector's Edition | Collectors who want physical items but play on PC. | Uses a Digital Premium Edition voucher code rather than a disc. |
PC requirements to check first
Should you buy on Steam?
Buy on Steam if your friends and library are already there, or if your PC is your primary platform. Choose Xbox or PS5 if a console physical disc or couch split-screen setup matters more.
