User Summary Containment: The Zombie Puzzler is loosly based on the match 3 style of casual puzzle game, except that here you are trying to kill zombies by surrounding them with matching units, e.g. Cops, Soldiers, Scientists or Thugs... you can also earn special attacks such as snipers, grenades and even airstrikes. The other thing that makes it a bit different from the usual matching puzzle games is that the zombies spread over time, infecting your units, so there is an added level of time pressure.
