Shoot the zombies, organize search parties to look for survivors and new weapons, manage your group to defend and repair your safehouse.
Tips:
Each survivor has its own set of skills. Use them wisely when distributing into parties. Have at least someone with higher fight skill in your search party, this will increase the survival chance of the whole party.
***BIG GAME, WILL TAKE A WHILE TO LOAD, PLEASE BE PATIENT***
