This category links to all of the Versus: Snowbound sets. Which are exclusive to the Target in the USA. These sets are similar to the Versus sets, but these sets are based in the snowy landscape of the Halo 3 Map Snowbound.
Description from the Halo Wikia:
"Snowbound is a medium-sized multiplayer map in Halo 3. From Bungie Q&A on a Weekly Update, they hinted that it may take place on a former Forerunner planet near Earth, though it is currently occupied and being excavated by the Covenant."
