Max Ammo is one of the original power-ups in Call of Duty Zombies, the co-op survival mode that debuted in World at War in 2008 from Treyarch. It drops randomly from defeated zombies as a glowing green box and refills all carried weapons and grenades for the whole team. The booming announcer line became a shared signal among players, instantly understood even without seeing the drop. Clips and edits later carried it beyond the game into streams and short videos, where it still marks relief, luck and a second chance.
