All by Oneself III was the third All by Oneself level of Far Future in the Chinese version of Plants vs. Zombies 2. The main objective of this level was to defeat hordes of zombies, just using one plant. When this level was finished for the first time, the player got a star.
This level is very difficult. The massive hordes of zombies can be difficult to kill, even though projectiles deal ten times as much damage as they normally do. The plant order also gets worse as time progresses. Kernel-Pult is very measly at defeating the Jetpack Zombies that appear first, followed by Laser Bean, which does significantly more. Lightning Reed is also a very good plant during the point it's on the Minecart. However, once Starfruit is on the Minecart, things get harder. Starfruit's unique shooting angles make it extremely hard to hit anything at long range and even short range. Finally, the Snapdragon is possibly the worst. While it does do plenty of good damage with Area of Effect, it is easily overwhelmed by Mecha-Football Zombies and requires short range. Once the Gargantuar Primes come in, be extremely careful. One laser will instantly knock out the Snapdragon, causing a loss. The Gargantuar Primes also requires ALL Plant Food to be used to defeat them. Knowing when to use Plant Food is crucial to winning this level.
