Deckalypse

Most deckbuilders hand you one hero and one deck. Deckalypse hands you four survivors and makes them share. A Tank to hold the line, a DPS to break it, a Ranged hitter to control the field, and a Support to keep everyone breathing. Each one builds their own deck and draws their own hand. Every turn you decide who acts and who watches.
One energy pool. Four hands. Never enough.
Eight cards land in front of you every turn, two per hero, and you can afford maybe three of them. Energy is shared across the whole party and it grows the deeper you push into a region, then resets when you move on. Early turns are small and surgical, with heroes passing entire rounds because the Tank needed that point more. Late in a region you finally have the room to chain all four together and delete a board in one turn. Then it starts over.
Position is a weapon.
Your party holds a front and a back row. Enemies close on you through three distance bands, and every card checks both, so where a hero stands decides which cards are even legal. Root something at the far band and it can never reach you, but now only ranged cards reach it. Taunt only works from the front row, so your Tank has to stand exactly where it hurts. Pull a bleeding hero back to save the run. Shove the Tank forward to win it.
A wasteland full of cards.
More than 130 cards are out there, picked up from combat rewards, traded in scavenged shops, torn off bosses who drop them nowhere else, and assembled from fragments scattered through a region. Decks cap at fifteen cards, so a full party fields sixty at most and you never see half the collection in a single run. Between bosses you can reshuffle which cards belong to which hero, or take them to the Forge and change what they do.

One bite and they are on a clock.
A common enemy called the Biter starts every fight already in your face. Its bite does damage, and it starts a fifteen round timer that does not stop when the fight ends. Resting will not clear it. Every round infected takes another 5% off that survivor's damage, all the way down to 90%, so your best fighter slowly stops being able to fix their own problem.
When the timer hits zero they turn. One HP, impossible to kill, target or control, clawing at the people beside them with a chance to pass it on. They are not dead. They are a problem you carry into the next fight, and if the last one standing is the turned one, the run is over. Block stops the bite from ever landing. Two cards and two items are the only other way out, and only one of them brings back somebody who already turned.
The trader deals in supplies, not cards.
You already earn cards from fighting. The trader stocks the things that keep you alive: medkits, damage and block stims, defibrillators to get a fallen survivor back on their feet, and the cures. Everything you buy goes into a satchel you carry on the map, usable between fights, with your party's infection status readable at a glance. Your gold and your supplies survive your death. The wasteland takes your run, not your savings.
Nothing you earn is lost.
Every enemy you kill drops resources that outlive the run. They go back to a permanent camp where you raise the party's energy cap, card draw, health and damage, rebuild a wrecked vehicle part by part into permanent bonuses, and trade your kills at the Gambit's Trade for relics that pay off the debuffs you were already stacking. Boss kills earn perk points for each hero's tree, respecced freely between fights. Sharpen the DPS into a glass cannon, turn the Tank into a wall, push the Support toward heals or hard control. You get stronger every time you die.

Six regions. Eighteen bosses. One road out.
The Streets, the Hospital, the Mall, the Parking Lot, the Rail Yard and the Highway, three procedurally laid out acts each, every act ending on a boss that can end your run. Bosses transform at half health with new patterns, new art and new energy, and the ones at the end of a region hex a hero on a cooldown with a curse that fires the turn after it announces itself. Clear a region and the ones behind it get harder. The road ends at the Overlord, one of the rotting kings that turned the world into this. Kill it, or join it.
There is something under the map.
Six hidden areas sit beneath the six regions, each locked behind a key buried somewhere in that region's second act. Down there is a mini-boss that is not in any encounter pool and a card that exists nowhere else in the game. Underground runs always start at a fixed seven energy, so the upgrades you bought upstairs will not save you.
Three crates a day.
The Spoils Den runs one skill minigame at a time and swaps it at dawn. Piece a torn photograph back together, walk a minefield by its numbers, or haul live cables to their breakers in the order the panel arms them. Win and you pry open a crate. Most spill resources, some are stuffed with junk, and a rare one hides a shot that sharpens your entire next run. Lose and you waste the crate, so play sharp.
A new run every day, the same one for everybody.
One seed, one region and a rolling set of mutators, handed to every player in the world at midnight UTC. Retry it as often as you like, because your best score for the day is the one that stands, and scoring counts the gold you earned rather than the gold you hoarded, so spending at the trader never costs you points. Steam leaderboards run per date and per region with your friends' scores in the rows beside yours.
Any run at all can be packed into a shareable code that carries the seed, the region and the mutators, so a friend plays your exact run instead of one that merely resembles it. Friends who are playing right now show up as live pins on the frontier map. The ones who are not leave a ghost where they were last seen.
