Halo Infinite has officially started its first Operation. These will essentially act as free mini-seasons lasting 4-6 weeks. 343 has based its first Operation around the Spirit of Fire to kick things off. For those unaware, the Spirit of Fire is the name of a command ship in Halo Wars. The armor that 343 is giving away for free is built around the Mark IV set, which was the gear the Spartans were wearing during the Halo Wars era.

Just like seasons, Operations can be claimed from the in-game store at any time, just in case players miss out on one while it’s new. But unlike seasons, Operations won’t have the 100-tier system most players are accustomed to. In addition, Operations won’t have any story cinematics to them and will instead focus on in-game content.

It’s also worth pointing out that even though the Spirit of Fire operation is free, you can still spend credits (Halo Infinites premium currency) to level up and unlock exclusive items. If you spend 500 credits on the Operation, you’ll unlock the Evolved MA5, a skin for the MA40 Assualt Rifle. But if you spend 2,000 points, you’ll obtain the rifle skin and automatically unlock everything.
