Zomboss gives a thumbs up. A single, confused Peashooter wiggles its leaves. Fade to black.
Simultaneously, across Suburbia, zombies begin acting strangely. Instead of mindless shambling, they form disciplined squads. Conehead zombies wield stop signs as shields. Buckethead zombies use their buckets as battering rams. Leading them is a new elite zombie: (a zombie in a cracked, sparking lab coat, holding a broken stopwatch). Where it walks, grass withers into gray dust, and plants age rapidly (a new mechanic: Chrono-Zombies inflict "Decay," which reduces a plant’s attack speed and health over time). plants vs zombies expanded and enhanced mod
Patrice returns from university. She stares at Zomboss, now wearing an apron and grilling tofu dogs. Zomboss gives a thumbs up
(takes a long, slow bite of a taco) “The harvest, Patrice. The harvest of understanding.” Buckethead zombies use their buckets as battering rams
“Uncle Dave… what happened?”
Zomboss pilots a new mech: The Chrono-Cephalopod (a squid-like machine with lawn mower tentacles). It doesn't attack directly. Instead, it rewinds time on individual tiles , resetting any plant there to its seed packet form. Dave must use a new plant, the Stasis-Starfruit (shoots projectiles that freeze zombies in a localized time bubble) to lock tiles in place.
