Why wait 'till August?
Looking at the Space Police sets, I realized I have all the parts I need for that spiked car, at least for what I would turn it into. After that, I just had to have a go at the police ship. They now each sit two.
Not your typical Peaceful Lego MOC, but it's worth noting that both crafts are unarmed. Those are all maneuvering thrusters. The only "weapon" the police cruiser has is FEMPP (focussed-electro-magnetic-pulse-projector), that can disable the systems on pursued craft, stopping it effectively.
