Raise the dead and build a horde that never stops growing. Undead Forever is a social zombie RPG made for quick check-ins and long rivalries: every mission, fight and payout adds to a monster that is yours forever. SURVIVE YOUR FIRST NIGHT Claw your way out of the morgue in a guided first night. Arm your horde, draw first blood, strike the Morgue Titan and take your first Mutation, with a reward waiting at dawn. HUNT REAL PLAYERS Discover rivals on the Fight board. Chain kill streaks through 13 tiers, from STREAK to UNDEAD FOREVER, for bonus Flesh, XP and titles. Post bounties on the Hit List, collect them, strike back at whoever hit you, and watch a repeat rival become your Nemesis. Read every fight blow by blow. Beat someone down and they land in the ER, protected until they heal. MARCH THE DEAD ROAD Six-stop campaigns through a ruined city. Choose how your horde crosses each stop, expose NPC commanders, storm their Strongholds and break the seals on Relic rewards. TAKE DOWN WORLD BOSSES The Morgue Titan, the Subway Broodmother, the Megawarren Colossus and the seasonal Crimson Butcher shrug off whole hordes. Everyone who draws blood earns the kill and a loot roll when the boss falls, and the final hit claims a killing-blow bonus. BUILD YOUR MONSTER Choose your Origin (Hunter, Rotborn or Broodmind), climb the Mutation grid, assemble your Horde Loadout of action, regenerative and enhancement abilities, set Lures that pay out Flesh every 50 minutes, and fill the Reliquary with relics earned on the road. RULE WITH YOUR CLAN Forge a crest from painted emblems, trims, colours and patterns, then fly it on your clan's war banner. Win the weekly clan battle for podium trims and the champion's crown, spend your War Chest in the Armory, and recruit with your own clan link. Every week's winners are carved into the Hall of Champions. A LIVING UNDEAD WORLD Talk with every zombie in World Chat, leave your mark on rivals' Walls, and chase 30 Game Center achievements and 4 leaderboards. BRING YOUR FRIENDS Share your invite link. Friends get a Flesh bonus, and you earn 77 LP for every friend who survives their First Night. Play instantly as a guest, then save your horde with email or Game Center whenever you like. Raise the dead. Settle the score. Build forever.
