Warhammer: The Old World uses square and rectangular bases, many of them larger than those used for previous iterations of the game of fantasy battles. If you want to rebase your venerable forces for the new Old World, you’ll want to pick up some of these sets. There are 11 packs to choose from, with every variation of base you could need, from 25mm squares for infantry all the way up to 100x150mm rectangles for the very largest of monsters.
