Warhammer. Warhammer never changes, as Wrong Perlman once said. But Dota 2 does, it changes loads, and its latest alteration is its support for Warhammer-themed items in the Steam Workshop. As that support was just announced yesterday, there are currently no Warhammer-themed items in the Dota 2 'shop, but I'm sure 3D modellers and texturisers are busy inventing them as I type this. Here's the Warhammer tag, looking all sad and empty.
An incentive to do so is the Call to Arms contest, which runs from now until the end of August, and will reward up to eight of the best entries with a coveted place in a new Warhammer-themed Dota treasure pack. They'll also get a load of Sega games, including Total War: Warhammer, along with all the other Total Wars. The rules are linked above if you fancy your chances, but the main one is that entries should abide by the "visual themes" of Games Workshop's series. Designers of big spiky shoulderpads and massive guns will be in their element, I reckon.
