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!
