Engineer (PvZ: BfN)

In Plants vs. Zombies: Battle for Neighborville, the Engineer is a Support class. His ability set from previous games has also been completely changed to better suit his support role; his Sonic Grenade has been replaced with the Bullhorn Swarm, his Big Bolt Blaster is now a deployable sentry turret called the Heavy Helper which shoots plants while also increasing the damage output of nearby zombies instead of a gatling ability, and his Jackhammer has been replaced with Double Time (while his Jackhammer is now his sprint). In addition, the Concrete Launcher's projectiles now bounce on walls before exploding.
