Pack-a-Punch is a game-changer when it comes to playing Zombies, as it helps you upgrade your weapon power significantly to dominate the constant horde of zombies coming after you. However, these upgrades cost a lot of Essence, and sometimes it becomes a dilemma whether to go for the upgrade or buy perks.

With the release of the new Zombies map, the Tomb, inCall of Duty: Black Ops 6, this is the first time we see a side Easter egg reward the player with a completely free Pack-a-Punch upgrade. In the Tomb, it’s not only possible but even easier to complete, so you should always complete this Easter egg in every match. It will save you up to 5000 Essence, which you can then use to buy perks.
