Zombie Trapped

Your team was sent to the Ammochostos General Hospital to find the Vaccine. Your team found it and alerted the WHO (World Health Organisation). A special forces team was sent to extract you.The landing pad on the roof of the hospital was destroyed by an explosion so the helicopter was forced to land on the ground. The noise attracted a second wave of zombies. On the way out, you were confronted by a horde in the passages. During all the fear and confusion, you split from the special forces team and are now barricaded in another room. There is no safe route to get out. You need to at the very least get the vaccine to the Special Forces helicopter.......or better still, your team to escape and get into the helicopter. Where is the Vaccine? You’re Trapped.......
