Games Workshop unveiled Warhammer Underworlds: Beastgrave - Arena Mortis, a multiplayer expansion for Warhammer Underworlds: Beastgrave, for release on September 26.

Warhammer Underworlds now features multiplayer combat in Arena Mortis which transforms the miniatures game into a free-for-all fight. Players can select their favorite champion and fight against two to five other players' champions in a battle royale. The box comes with 20 all-new Gambit cards, 20 all-new Upgrade cards, a double-sided game board, tokens and cards, and updated cards for the Restless Dead gambit and the Sepulchral Warden.

This set will retail for $45.00.

Games Workshop recently released two warbands for Warhammer Underworlds: Beastgrave, Morgok's Krushas and Morgwaeth's Blade-Coven (see "Games Workshop Announces Two More Warbands For 'Warhammer Underworlds: Beastgrave'").
