I didn't manage to get a test game of Gruntz on Tuesday at the local club due to a mix of falling attendance as the summer break approaches and people already being spread out between a lot of systems. However I did manage to take a few photos of the forces so far on our desert plateau Infinity table.
The 30mm polystyrene plateaus work well for both 28mm and 15mm figures, for 15mm they are even tall enough to hide vehicles in the ravines.
