Gradanix

Gradanix is a permadeath co-op action RPG roguelike. Players pick one of seven classes - warrior, paladin, rogue, hunter, mage, priest or warlock - and descend through an endless, procedurally generated dungeon that grows harder with every level, with a boss encounter every seventh floor. Death ends a run permanently, and the depth reached is the score, recorded on global leaderboards that run in three-month seasons. Runs can be played solo, in online co-op or over LAN, with experience shared evenly between party members. An optional Corruption dial increases enemy difficulty and rewards, the first player to find each legendary item is recorded permanently as a world first, and characters keep their level, talents, bank and personal house between seasons.
