Seismograph

The  is a a tier 5 tank that upgrades from Oscilloscope at level 60.

Design
Same design as the Oscilloscope, but the "wedges" on the sides are red, and a red spike is added to indicate that the tank shoots accelerating bullets.

Technical
Very high FOV, like the Oscilloscope. However, its big difference is that the bullets are accelerating, like the rainmaker.
