Far Future - Day 29

Difficulty
This level has a unique ambush attack, in which the Sap created from Sap-fling causes a Necromancy-like ambush. Defeating zombies quickly should be done so that the ambush zombies are less of a threat. Holo-Head Zombie is among the ambush zombies. There are also Mecha-Football Zombies to mess up defenses, and Disco-tron 3000s to put pressure on the field.
