Pre-orders are due this week at my distributor for the Dropzone Commander Cityscape boxed set. I know you use these for Robotech Tactics. The set is supposed to be out soon.
If you are interested, please PM me or post here ASAP and I will pre-order it for you.
Da King mentioned a Ruined Cityscape set. I do not see that in the catalog currently, but I assume it must be coming along later this year.
Thanks
