United Kingdom, Oct. 7 -- Bungie is inviting fans to participate in a technical test of Marathon.

The upcoming sci-fi shooter has so far had a rocky development and was delayed, but Bungie has now announced it will be running a closed technical test of Marathon in North America and Europe from October 22-28.

In a statement, the studio wrote: "This is an important checkpoint for us as we test our improvements since Alpha, including three maps, five runner shells, prox chat, re-tuned combat pacing, solo queue, deeper environmental storytelling, and more.

"That said, the Technical Test build is a work in progress and will only include a portion of what's planned for Marathon's full release, focused on the early player experience."
