So I decided to put something together after seeing a sad lack of arctic maps (especially if we discount maps that use the arctic theme instead of snow hexes. The end result was a goal: build the equivalent of a modern CGL Map Pack (12 unique 16x17 maps) with an arctic theme, including appropriate hexes. The end result was...
Fan Pack: Arctic

FP:Arctic includes 12 mapsheets that can all connect together, even when using more than the 6 mapsheets that would come with a double-sided set of physical maps. At the same time, though, it does still use the double-sided nature to have two different types of environments on offer...
Arctic Fields: A series of battered trench lines and occupied vacation homes are all that stand between a remote arctic research facility and a wave of oncoming invaders.
Arctic Mountains: Nestled deep within a snowy mountain pass, an ancient fortress sits, supplied only by the nearby cliffside airport and a difficult dirt path.
These maps are available as singles, in an 8-mapsheet BFM-format, a massive 12-mapsheet MOAM (Mother Of All Maps)-format, and nearly a dozen other pre-arranged configurations that can provide a good play space even when randomly selected.
Fan Pack: Arctic will be included in an upcoming MegaMek release, but if you'd like you can download it below and give these maps a whirl ahead of time! Naturally, any feedback would be lovely. Either way, hope you enjoy them!
