The Surge Base has double the range of the Doge Base, and creates a devastating level 3 Surge Attack instead of a Wave. It deals 96,000 damage per hit in all of its appearances, and can spawn between 150 and 2,000 range; a huge area unfortunately paired and evened out in favor of the base as all created Surges have 125 outward piercing range and 250 inner range. Like other bases, it is immune to all negative effects.
While it does use a laser to telegraph when the surge is about to go off, the laser does not indicate where the surge will happen. There is no way to know where a surge will erupt until it already starts erupting. Additionally, when it fires the surge, it hits a Cat Unit in the front to do so, regardless of where the surge itself will erupt. Beware the telegraph, as you will have only 15 frames or half a second to prepare before the Surge spawns.
Because of the Surge Base's insane damage output, units hit by the attack or Surge will most likely either die or be close to dying. The Surge also acts like a temporary wall that deals heavy damage to units that touch it. This can be avoided by luring enemies close to your base, away from the Surge Base's range. Alternatively, you can use Surge-Immune units such as TalentedBeefcake Cat, Idi:N2, Elder Mask Doron, and Jagando Jr.
