New early version of the marble fightback level, there are various boxes the marbles can pick up to help them fight off the zombie hoard.

The marbles are doing science things and zombies don't like science, lets hope they don't escape. The marbles must make their way to entrance of the bunker to escape. On the way they can use any office and science things they find to block the zombies way.
