Grimslingers: Advanced Duels is a micro-version of Grlimslingers, a strategic sci-fi western fantasy epic, and features a taste of both the versus and solo/co-op game modes. In Advanced Duels, players will face off using the elements and special spells called signatures to outthink, outwit, and outmaneuver their opponent. Players may then go solo or join with a friend to face a simulation of the legendary "Witch King", which will test them like no foe ever has before. —description from the publisher
