The EMP shell is a type of mortar shell that upon exploding in an EMP burst.
Acquisition
EMP shells are made using 15 steel and 2 components at a machining table and requires Microelectronics to be researched. Requires a Crafting skill of at least 4. The steel cost is increased to 25 if the Classic Mortars difficulty option is enabled.
They can also be purchased from traders.
Summary
The EMP shell deals 50 EMP damage in a 8.9-tile radius, stunning mechanoids, turrets and other mortars for 25 seconds, and instantly downing shield belts, low-shield packs 
, mech low shield
After being stunned, mechanoids become 'Adapted' and gain immunity against further stuns for 2,200 ticks (36.67 secs). Immunity is applied on stun, and will not be extended by stunning an adapted or already stunned mechanoid.
Analysis
It is a niche weapon that is extremely good at whatever it does- downing shields and stunning mechanoids. Because of this, it finds really good value even though it deals no physical damage whatsoever.
Due to its large blast radius, only a few shells are usually required for each barrage to hit all enemies. Given that, as well as its combat effectiveness, it is a very cost-efficient choice, despite requiring components to make.
Version history
In 1.1 its crafting cost was increased (20 --> 25 steel, 1 --> 2 components).
- 1.3.3066 - Steel requirement decreased from 25 -> 15 unless Classic Mortar difficulty option enabled.
