Warden's Descent is a 1-4 player co-op dungeon crawler about extraction pressure: everything you loot is only yours once you climb back out. Die down there and it stays down there.
Descend 44 gauntlets across a 99-floor campaign and three realm forks (the Salt, the Icy Depths, the Marrow) with a bestiary of over 250 enemies, a guardian at the bottom of every gauntlet, and a shared Sanctum to bank it all in.
Every floor is dealt fresh, and some arrive with an omen on them: FLOODED, LIGHTS OUT, BLOOD PRICE, THE SWARM, GILDED, HAUNTED. Bring friends: a full party of four can carry one under-levelled friend who keeps the loot but not the progress.
Wishlist it and you'll hear the moment it releases. Online co-op, LAN, 52 Steam Achievements and Steam Cloud on day one.
