Boxhead: A Halloween Special

This is the first Boxhead game. It was released as "A Halloween Special," but it definitely stands on it's own as a full-length high-quality game.

In Boxhead - A Halloween Special, Boxville has been overrun by zombies! It's up to you to lead the town's civilians (the blue guys) to safety while defending them from the zombie onslaught! Luckily, you'll find several types of weapons along the way to help you keep the zombies at bay.

Carefully make your way through the town to find all of the civilians, and have them follow you to the evacuation point. Not only do you need to keep yourself from being killed by the hordes of zombies along the way, but you also need to keep the civilians safe as you make your way to the evac point. This isn't an easy job, since the civilians have a tendency to wander off or get scared and run away.
