Gauss Discharge

As the description says, the Gauss Discharge combines a regular damage effect with a debuff to enemy units' evasion. It can be produced at your artillery factory once the corresponding Gauss technology is researched, and requires at least a level 12 artillery factory. It costs 400 ammo and 300 ionites, and takes 50m to create.

Note that after being activated, it takes a second or so to actually go off, so be sure to take this into account while aiming.
