• MR 30 - This is a survival mission, which means that killing enemies quickly is important. One quirk of the level is that you have unlimited ammo. I went with Wukong, with a fast melee weapon, and the Bramma equipped by the clone. At the end of each wave, you'll encounter a set of "boss" enemies, including a nullifier, so you'll need to be able to kill them without using abilities.
• MR L1 - This is a harder version of the MR1 test. You'll have to kill enemies using only your primary weapon, without using any warframe abilities. I went with Nidus for his high armor, and self healing passive.
