[Counter-Strike Nexon: Studio] Zombie Scenario: Season 1, Double Gate [Hard Difficulty]

Once the continual zombie attacks from the city center
ceased, the troops quickly made their escape. Attempts to
communicate with the outside world were hopeless,
confirming the troops were on their own. To find the cause of
their isolation, they investigated the area.
During their search, the troops found two people wearing
protective gear near some waste. When the troops called out
to them, they made a hasty escape with their equipment. The
pursuit lead into a nearby building but all that remained
inside were scraps of equipment.
With the trail having gone cold, the troops collected the
damaged equipment and left the building only to meet the
eerie shrieks of zombies. The troops realized that the zombie
were close at hand, and hastily created a barrier using
material from the construction site to prepared for battle.
