A city wide disaster drill and SF State's Campus Safety Awareness Week activities were interrupted by a group of student zombies roaming around campus on Thursday.

SFSU Improv Nation performed their third annual "Zombie Walk," in hopes of promoting their organization and their upcoming events. Approximately 50 students attended the zombie apocalypse during the four hour event.

Some zombies even helped with the demonstration for the Safety Awareness program.

This year Improv Nation used theater blood, something not used in the past, to create wounded effects on their bodies.

Travis Northrup, a BECA studies major and president/founder of SFSU Improv Nation, said the group was much smaller this year but more enthusiastic.

The group ended their event with a "Thriller" dance at Malcom X Plaza.
