Starting with Region 32, Assault will now feature classic favorite maps from previous regions serving as the assault maps for new regions going forward. This frees up development time to work on other exciting new content.
Don't worry! Even if the maps appear to be older maps, they'll still pay out according to the region you play them on, so you'll get the correct buck amount for playing them. As such, they'll also require the correct region level of weapon in order to play them.
