Halo 4 is on the horizon, and if new registered domain names are any indication, Microsoft may also be planning something related to Halo Infinity. Master Chief: To infinity and beyond.

　　As spotted by Fusible, several Halo Infinity domain names were registered this week, including HaloInfinity.net and HaloInfinityMultiplayer.com. The Web addresses were registered through Mark Monitor, a brand protection agency, which counts Microsoft among its clients. As Fusible points out, Microsoft.com is registered through Mark Monitor.

　　None of the Web pages are active as of press time.

　　Infinity was a multiplayer level that was released only for the PC version of Halo: Combat Evolved. It is also related to UNSC Infinity, a vessel that first appeared in the Halo: Grasslands novel.

　　A Microsoft representative told GameSpot, "Microsoft often acquires various domain names as part of its ongoing business strategy, but beyond that we have no comment." Halo 4 is due out on the Xbox 360 this holiday season. For more on that game, check out GameSpot's latest coverage.
