Ice Man

One of a large number of Plants vs. Zombies games to come out of China, Ice Man puts the player behind a real-life water gun to try to stop a horde of incoming zombies. As the stream of real water hits the screen, any zombies who are hit get progressively more encased with ice; freezing them slows their advances, and shooting them while frozen will eventually kill them outright. The player's performance is rewarded with redemption tickets.
