Quester

 is a Tier 5 Tank that upgrades from Annihilator and Tri-Trap Guard at level 60.

Design
The has an identical gun to the Annihilator on the front and an identical gun to the Pounder on the back. To either side of this rear Pounder gun, it has two trappers turned 45 degrees away from the Pounder.

Technical
This tank has a unique control scheme. When firing, only the Annihilator and rear trappers will fire. When using altfire though, only the rear Pounder will fire allowing the tank to boost itself.

This tank has undergone multiple revisions to its control scheme across the game's many updates and incarnations. At one point, both its rear trappers and Pounder were controlled by altfire, and another point it was reversed so only the Annihilator cannon used altfire. The versions of the games containing either these have been lost though.
