MK1 Madness

Rules

Tenno will attempt this challenge on Ani in the Void.
You may compete in one of two tiers: Spartan (no forma, no potato, no riven) or Elite (formas, potatoes, and rivens allowed).
Abilities are banned. After much deliberation, this will include Spoiler Mode as the game counts its use as an ability.
Only MK1 weapons are permitted.
Companions are allowed, companion weapons are not.
You will provide screenshots of your weapon builds as well as the mission complete screen. The mission screen must show the abilities used line.
