The Critical Countdown event in MW3 and Warzone is currently underway. This limited-time event brings players unique rewards that are both cosmetics as well as consumables. The objective of this event is quite simple. Players must collect DNA samples from eliminated foes or teammates, or from loot caches (Warzone). When enough DNA samples are collected, they get a reward for each milestone reached.

These DNA samples have a name and there are a total of four different types to collect. However, at the time of writing only two are available and the remaining will unlock as the season progresses.

Having said that, this article will take a closer look at the new limited-time event in MW3 and Warzone, how to participate in the event, and all the rewards it brings.

The Critical Countdown event in MW3 and Warzone requires you to collect DNA samples from fallen foes or allies, or by opening loot caches in Warzone. At the moment, only two strands of DNA are available in the games and they are called Ade (blue) and Cyto (orange). However, there are two more different strands of DNA (yellow and pink) in the event, which will become available later.

To participate in this event, simply drop into any game mode of your choice. All the enemies will drop their DNA samples upon elimination. You must walk over them to collect and once you have collected sufficient amount of DNA, you will unlock a reward. Alternatively, in Warzone you can also find them in loot boxes.

But that's not all. Once you have collected enough of all four DNA samples, which are also called Mastery Challenges, you will unlock the final reward of this event, which is an animated camo for the FR 5.56 Assault Rifle. Check the section below to see all the rewards you can earn in this event.
