Matryoshka Doll

Start a Tier I+ Cursed match on Astra Malorum. Bring C4 and survive to Round 40. Progress the Main Quest until the portal to Mars is unlocked.

Travel to Mars. Find the central circular platform/altar. Locate the 3 pieces of meat around the outside edges of the circle.

1. Place C4 on top of each piece of meat.
2. Lure a large horde of zombies onto the platform.
3. Detonate for a large number of explosive kills.

Tip: Wiping a full horde in one detonation usually suffices. The exact kill count required is unconfirmed.

A yellow portal spawns in Machina Astralis near Thurston\'s Cryopod.

Enemies can only be killed while using a Field Upgrade (they auto-recharge every ~15 seconds).

• Use War Machine scorestreak against HVTs.
• Frenzied Guard with Frenzy Fire Augment gives you infinite stock ammo + extra armor.
