Halo 4's executive producer has said that Microsoft is considering the introduction of microtransactions in the game.
The news comes as the last piece of DLC included in the game's Season Pass – the Castle map pack – is released worldwide.
"I think Halo certainly has the potential for those kinds of things," Dan Ayoub told Digital Spy of the small microtransactions now available to players of Gears of War: Judgment.
"We don't have too much to talk about in terms of our plans down that line, but it's certainly something... we've seen the fans of Gears are enjoying, and if it's something we think our community is going to enjoy, it's something we'll seriously talk about.
"Obviously our commitment is always that we're going to make sure there's something for people to do on Halo, whether it's playlists, or new maps or new content, something like that.
"We can't say too much about the specifics we're planning, but what we can say is we don't take that commitment lightly, and people should keep their eyes open for cool stuff."
Microtransactions were introduced to Activision's Call of Duty: Black Ops 2 last month.
