Griefer

The  is a Tier 4 Tank that upgrades from the Destroyer at level 45.

Design
The has a tapering barrel similar to the Stalker, but it is proportioned like the Destroyer's barrel. It also gains a triangular prop on the top of its body.

Technical
As indicated by its barrel and prop, the Griefer can become invisible. Compared to other invisible tanks such as the Stalker and Landmine, the and its branches take much longer to become invisible.

As the

 * Try and find a good spot to go invisible, somewhere not too populated but that still gets traffic.
 * You can also play it like a normal Destroyer and only use your invisibility defensively, such as after a failed attack or hiding from pursuers.

Against the

 * Griefers are extremely dangerous, the most dangerous invisible tanks by far.
 * Look very closely to try and spot one before actually getting close. If you get close, you are more than likely dead.
 * If you are particularly paranoid, use a Minesweeper branch or Seeker to spot it out.
