The newCall of Duty: Modern Warfare 3Zombies mode is a bit daunting compared to previous modes. In total, there are three separate Acts to progress through when playing Zombies. However, the final two acts of Zombies are locked. This is how to unlock Act 2 and Act 3 of Zombies inMW3.
Unlocking the other Acts
In order to unlock Act 2 you must complete all six Tiers of missions in Act 1, which must be completed in order. For example, you must complete all Tier 1 missions to unlock Tier 2, and then all Tier 2 missions to unlock Tier 3. Once you’ve completed all the Tier 6 missions, you will unlock a final Story Mission. Completing the final Story Mission for Act 1 will unlock Act 2 and give you access to all the Act 2 Tier 1 missions.
From here, you will need to complete all six Tiers of missions and the Story Mission of Act 2 to unlock Act 3. For now, it looks like Act 3 is the final act for Zombies inMW3.
What are the rewards for completing Acts inMW3?
Each mission in all Tiers grants you a reward upon completion. Some rewards are just icons, emblems, calling cards, and more, but others are items that you can use in Zombies. For example, a lot of the Tier 1 missions for Act 1 give you Jug-a-nog which you can consume for health boosts.
The later Tiers give better rewards, which probably means future Acts will give even better. Even though you can prioritize which missions you take based on the rewards you want, in the end you will have to complete all missions.
With this information, you should now know how to unlock Act 2 and Act 3 of Zombies inMW3. Simply keep completing missions and unlocking new tiers until you reach the final Story Missions.
