Coilcannon

The **Coilcannon** is an imprecise weapon that can be considered as an upgrade of the Railgun. Unlike the former, it splits into fragments upon touching down on a planet which deal more damage, albeit with a smaller AoE radius.

## In-Game Description

*A yellow, heavily armored vehicle stops at the edge of a large, barren field. Two adults climb out, followed by a large group of teens. Everything happens in orderly fashion, and the loud noises and chaos one might expect are nowhere to be seen. The group takes position in front of the adults, in almost militaristic fashion.*

*One of the adults makes a gesture towards the field, behind which stands an immense structure. It must be a few kilometers away, yet it casts a shadow on the group. Though the barrel has already been dismantled by gigantic, sturdy cranes, one may still recognize the iconic shape of a railgun. Partially similar, but more modern-looking parts are unloaded from an equally massive cargo train next to the site. Finally, one of the adults starts their lecture.*

*"Railguns are, or I should say were, the cornerstone of interplanetary artillery. But important as they are, cornerstones are only any good if you build upon them. Though the core principle or their operation Is as old as that onthe ralgun, colguns started appearing on the battlefield only a few decades ago, as our technology progressed.*

*"After the first few prototypes proved superior, we started building more of them, often replacing destroyed or simply outdated railguns, as we see here. Coilguns still eat electricity in the same quantities as railguns, but they are more efficient, allowing us to launch bigger projectiles at much greatel velocity. One could almost say that…"*

*An alarm sounds from the loudspeakers mounted on top of the armored school bus, and immediately the youngsters rush back inside. There is no sign of chaos or panic; clearly this is something they have drilled for countless times. The vehicle speeds off, heading for the closest shelter-certified tunnel. The next lecture will be on planetary defenses in operation.*
