Engineer - How to play and some tricks

Another tactic which one should bear in mind is that with the exception of the Mechanic the Engineer class deals Splash damage.

While it is always worth your time and effort to go for the direct hit, which will be a critical hit, sometimes the tactic which benefits the team the most, especially when Zombies are the assault team,  is for the Engineer to stand off at a distance and simply lob shots into the Garden in order to deal Splash damage to anything in it. This is incredibly useful at clearing Potato Mines, Spike Weed and other traps or obstructions like Tallnuts but it will also damage groups of Plants or Potted Plants which might be relatively close by as well as scoring the occasional direct hit on a defender.

Sometimes the chaos caused by an Electrician or Welder standing at a good distance away sending indirect fire into the capture point dealing electric or fire Splash damage can be what breaks a heavy Plant defense.
