Iconoclash: LevelMAX is a stand-alone expansion and features 4 new, cross-over fighters for the Iconoclash system from Level 99 Games:

Zsolt: This relentless hunter never ceases, releasing his flurry of attacks with his arsenal of weapons. There’s no escape!
Khadath: The master of the portal takes to the battlefield and assumes control. By summoning his Gate Trap he can attack from any range.
Deques: Is your deck ready and do you want to duel? After studying the meta game for years, Deques has readied his deck of trading cards for any situation. Summon all sorts of monsters to become the champion!
Esfir: Bring down the house with this hothead who controls gravity. She sends her opponents flying into the stratosphere, creates blackholes, and inverts gravity with a snap of her fingers.
In LevelMAX you'll take the fight to the world of Seventh Cross with Mansion of Darkness and the Gilded Foyer maps.
