The House of the Dead/Chapter 1

Think of this level as a practice round. Shoot the heads of the zombies to get though the level. Save the man on the bridge to get an extra health. Save four people for more health.

Boss: Chariot
The first boss is a giant knight. Shoot the hole in his armor to kill him. After shooting enough, the armor will blast off and a slimy monster comes out. Shoot the slime off him to kill it. To make sure he will die, don't stop shooting the hole and you will survive.
