The Warhammer Herald asks players to go to Only-War, Warhammer Alliance or Warhammer Vault and choose between 3 mousemat designs, the winner of which will be available in shops when the game launches. Voting closes on 16th July (cue speculation about time to mass produce and send to retail stores in time for release).
The call is only on the US site currently, so this may well apply to US retail stores only. But whatever – they’re cool designs (and for the record, I like the Warrior Priest one best!)
edited to add: Looks as though everyone else likes the Warrior Priest too, it’s way in the lead on all three sites!
