The Act 2 Tier 2 Reaper mission in Call of Duty: Modern Warfare 3 Zombies is crystal clear - obliterate three elusive Harvester orbs and collect 15 items from them. Now, these orbs won't be immediately visible on the map when you spawn into the game. You will have to explore the surroundings, and only then will their icons reveal themselves.

You will need to keep an eye out for the unmistakable Harvest orb icon - a moving target with the name "Harvest" on it. It looks like an orb on the map, and has circles around it.

Efficiently destroying these purple orbs poses the primary challenge, as each boasts a health pool that demands quite a lot of time and bullets. Notably, they demonstrate erratic movement when hit, which necessitates precise aim and strategic adaptability in the face of the undead in Modern Warfare 3 Zombies.

With successful hits, these orbs will drop a generous amount of Essence, a valuable resource that is key to achieving the 15-item-collection goal.

Another thing to keep in mind is that chaos attracts the undead in the game. Therefore, while focusing on destroying orbs, it's crucial to be prepared for zombie interference. Striking a balance between eliminating orbs and fending off the relentless zombie horde is necessary in Modern Warfare 3 Zombies.

You must also exercise caution regarding the orbs' tendency to vanish if left undamaged for extended periods. Juggling between killing undead and the damaging the orbs ensures that they stay moving until destroyed.
