As you can guess by some ingame shots Arnor will be playable in the mod.the work on them has been little since all i have done to them is make the campaign arnor fraction playable and i added a few heroes from other fractions.

just tell me if you want arnor in all skirmish maps or just arnor and angmar related maps
No mod I know of (except the RJ, but it's dead) has a fully playable Arnor faction. So Arnor should be in all skirmish maps IMO.
My mod has fully playable arnor.I took few buildings from RJ
