We recently picked up some Old Crow 6mm Hammer’s Slammers vehicles and Plasmablast 6mm vehicles. Both lines are very nice and a great addition to any 6mm sci-fi force.

6mm Slammers - Packaged
The Old Crow Slammers’ models are cast resin bodies with metal turrets and bits. The resin casting quality is simply the best we have ever seen. The casting is even better than Spartan Games’ models but the vehicles do not have nearly the level of detail of Spartan or ForgeWorld miniatures. But there is almost zero clean up needed for the resin and only a tiny bit needed on the metal bits.

Top Comparison
As you can see from the photos the models scale well with other 6mm vehicles. The design of the hover models does make them appear a bit large because the hover skirt (plenum chamber) sticks out all around the vehicle but if you look at just the actual body of the vehicle you will see it fits right in with the others. In general a lot of the GZG stuff is a tad small and the GW Epic stuff is a tad large.

6mm Strike Hovercraft and Landing Craft Hover
We also couldn’t help ourselves from grabbing a few of the Old Crow naval minis. These are also extremely well done resin casts and are quite large. As you can see the Hover Landing Craft can easily carry one or more 6mm vehicles. Now we just need to think up a good scenario for them.
The Plasmablast models are all metal castings and are also extremely well cast. Only the smallest amount of cleanup is needed. Plasmablast has the Progenitor tracked line and the Orbital Combine grav line of models. Both are nice looking, unique, and quite complete lines of units.
As you can see in the photos the Orbital Combine medium grav tank fits in well with the other figures and the heavy grav tank fits even better.

6mm Landing Craft Hover with Hammer's Slammers Blower Tank and Strike Hovercraft
Both companies responded quickly to our order and everything was well packed. Note, Old Crow is very busy and a bit behind on orders but they keep you well informed of progress.
If you are looking for some good rules for 6mm sci-fi look no further than Strike Legion and Gruntz. Both are outstanding sets of rules.
