Enter an infected zone called "Romero E5". Don't let zombies spread over the city's borders by assigning soldiers to repair barricades and shooting at incoming infectees.
Your base is under attack by enemy soldiers and your job is to defend it with everything you got! Can you hold down the enemies and defend the fort until the 19th day has passed?
Command up to 3 defenders where there will be tons of enemy waves that will try to destroy your base. Equip a variety of weapons in which you can unlock and upgrade as you advance in the game.
