Antumbra

The **Antumbra** is a Tier 4 Air Unit on Serpulo obtained by upgrading a Zenith using the Exponential Reconstructor. It shoots barrages of varying bullets and missiles at any target and flies over walls, prioritising the destruction of generator-type blocks like the Combustion Generator when under AI control.

It can be further upgraded into an Eclipse, by directly inputting the Antumbra from the Exponential to the Tetrative Reconstructor.

## Strategies

### **Against**

The Antumbra's health and armor render your previous best anti-air, the Scatter, completely useless. Without the heavy firepower of anti-ground turrets, you need very high damage to take one down before it starts ravaging your base. Like other offensive Air Units, the Antumbra hovers at a set distance from its target, meaning that it avoids the detection of some turrets without lots of Parallax to pull it in. The Fuse is a perfect complement as a small group will shred it within seconds. Alternatively, the Cyclone and Swarmer have enough damage to kill the Antumbra, especially if using Surge Alloy as ammo and a Tsunami with water for bonus damage. The Foreshadow is also great against it if you have managed to produce Surge Alloy.

### **For**

While the Antumbra does a solid job being a fat and powerful version of the Zenith, it cannot match the unparalleled speed, destructive power, and utility that the Quad brings to the table. Since killing off other Air Units is not a big priority, there is no reason not to use the Quad over the Antumbra. Its rather middling speed makes the ever-present Foreshadow a nightmare to deal with. What the Antumbra has over the Quad (besides durability) is its ability to not get completely nullified by Force Projectors. Since Antumbra's weapons don't purely deal area damage, this allows it to destroy the shield of a Force Projector allowing for further destruction. While this does give the Antumbra the slightest of niches, Force Projectors that would halt Quads are never present around the Cores of enemy bases in the campaign (with the only sector even having them being Planetary Launch Terminal), meaning this would realistically only come into play for custom maps.
