Heavy Helper is an ability for the Engineer in Plants vs. Zombies: Battle for Neighborville. When activated, Engineer creates a sentry turret that also increases the rate of fire of nearby allies' weapons by 25% as well as replenishes ammo. Only one can exist at the same time. If the Heavy Helper is destroyed, a 16-second cooldown will be imposed on the player.

Placing the turret near a Dr. Heals will allow it to keep up the turret's health as well as give allies using the damage boost an additional healing effect. This works well in Graveyard Ops. In addition, the extra ammo Heavy Helper can give is astronomically high to the point where the Engineer can simply spam his primary weapon without consequences. This is also true for Electric Slide. It is advised not to leave the Heavy Helper alone, as its attack isn't very powerful. Its usefulness lies in the boosts it gives to nearby zombies. Placing it inside of a Dummy Shield will not only protect it but grant a boost to all protected zombies. This is useful as you won't be able to use the turret again quickly if it gets destroyed. Heavy Helper can only last 2 minutes after being placed down and will disappear after the 2 minutes.


  • It shares its attack name with that of the Big Bolt Blaster.
    • Its appearance is also a simply automated version of the Big Bolt Blaster with a camera attached and its seat replaced.
