What might Halo Infinite's microtransactions look like?

[Windows Central]

We know Halo Infinite has microtransactions, but what will they be like?
Halo Infinite is the next big Halo game coming to Xbox One and Windows 10 PCs, but a recent a job application description for 343 Industries revealed a potentially disappointing development: the game will have microtransactions.
This immediately got fans worried that Infinite would follow in Star Wars Battlefront II's controversial footsteps, but luckily, 343 Industries' Studio Head Chris Lee spoke out on Twitter, clarifying that Infinite will not have paid loot boxes.

Keep the faith, it's appreciated! We're still working through final plans and will share more when we are ready, but I can definitely say that Halo Infinite will not include real-money loot boxes.
