Of course, you could use them for any game you wished.
From the announcement:
Two new designed for infinity battle mats from Micro Art Studio – Icestorm and Warehouse are available in on-line store.
Size of both mats: 48inch x 48inch
The mats are a mixture of polyester and rubber.
Top part is a high quality printout on polyester surface. The bottom part is made of rubber thanks to that it does not slip.
It’s similar to the “mousepad” material.
The colour of printout may vary little compared to the ones shown on the picture.
The buildings, resin terrain, miniatures shown on the other pictures are not included and are just samples of quality you can expect.
