- Place ninja on map

Protect the temple from the zombies, fighting them with your ninjas! Start off with the Shuriken Ninja and upgrade it once and it should give you enough firepower to last through a few levels. Then if you can’t get the next level upgrade in time, buy a basic ninja to help with damage. Do this until you upgrade the Shuriken Ninja all the way to six and then buy and start upgrading the slow ninja.
