free mmo zombie game

Urban Dead is a free-to-play browser-based multi-player game where you play the survivor or victim of a zombie outbreak in a quarantined city centre, alongside tens of thousands of others.

In death, the city stirs. Its borders still locked down after a sudden government quarantine last year, Malton's trapped civilians make their way through the derelict buildings, surviving the winter to rebuild their fragmented society from the rubble upwards. Military cleanup squads patrol the empty streets, stationed in the city for the long haul, while embedded scientific groups continue the experiments that brought them here.

And the dead rise up and thrive, trailing through the ruined streets of the city, milling between buildings and clawing through makeshift barricades and diversions, reclaiming the city as their own.
