The Call of Duty community will have the capability to help the next game in the series grow in ways the developer never predicted.

Publisher Activision and developer Treyarch plan to add modding and map-making tools to the upcoming military shooter Call of Duty: Black Ops III for PC. This means that fans will have a way to quickly create game modes, arenas, and more. While Black Ops III is due out later this week, these PC tools won’t roll out until 2016, according to Treyarch. This is the first Call of Duty to get official mod tools since Call of Duty 4: Modern Warfare.

The mod initiative should provide Activision with a way to keep players, at least on PC, engaged with new, community-driven content into next year. And that, in turn, could keep the community spending money on in-game content like new official maps and more — especially if that Treyarch-produced content is necessary to get some mods to function.

If you’re wondering when you’ll get a chance to try this stuff out, it doesn’t sound like Treyarch will have it ready any time soon. It is aiming for a closed alpha test by March, with plans for an open beta some time after that.

The studio also explained how mods and player maps will work in the competitive game — after all, mods could give some players unfair advantages.

“We will include unranked dedicated server files with the tools so you can run servers with modded content anywhere you choose,” reads a Treyarch blog post. “We will [also] provide an unranked server browser so you can easily find and join servers with modded content.”

But while Treyarch is making this announcement and sharing its plans, it also wants fans to know that it isn’t making promises about what exactly it will deliver.

“Please remember that this is software development,” reads the blog. “So things don’t always work out exactly as planned. Sometimes features slip or drop off altogether. Sometimes they get replaced with other, more awesome features as we hit into limitations of our original plans.”

Moving forward, Treyarch says it will share more details about the development of these tools in the lead up to the open beta.
