So, after browsing the Infinity forums I found a great idea for quick terrain for Infinity. I stole this idea and ran with to see what I could do. In the same fashion as other terrain I am working on, it is incredibly basic. I will detail it later.
I started with a pile of these paper mache craft boxes from Hobby Lobby.
Oh and the added bonus, if you glue the lids to the bottoms and not the tops they stack and make it easier to move around.
As for the type of terrain they provide, good multi-level line of sight blocking terrain. There needs to be some small scatter terrain, but as it stands it should get the job done.
