Blueprint or Made Up: Blueprint
Components: Military engine with repeater, survey charge with default tip
Attachments: Explosion amplifier
This one's a real classic: a rapid-fire assault rifle on top with a bottom-mounted grenade launcher. Make sure to include the explosion amplifier to maximize the radius of those grenades. We recommend upgrading the grenade launcher's clip, as well, unless you want to have to reload after every two shots. And you can swap the default tip on the survey charge for a diffraction torus to get incendiary grenades instead. Woohoo!
