A new dungeon every week, built by the server floor by floor. Press E on an Abyss Gate to start a run. Clear every zombie on a floor, then E on the glowing exit to bank its loot and go deeper - traps, lava, tougher zombies, and a boss every fifth floor. Die and you lose everything you banked. /abyss leave at a cleared exit takes you out with it.
Nobody has gone down yet this week.
