MW3 & Warzone Critical Countdown event: All rewards and challenges

Season 4 of MW3 and Warzone is in full swing with lots of new content and with it comes the new Critical Countdown event that’s giving players free rewards including a new blueprint. So here’s everything you need to know. 

New weapons like the Reclaimer 18 and Superi 46, new maps like Tokyo and Paris, and the reintroduction of Advance Warfare’s DNA Bomb Killstreak are just some of the few things that are refreshing the game in Season 4 of MW3 and Warzone. 

One other new aspect is the Critical Countdown event, giving players a chance to net themselves some rewards and even a free blueprint. 

When does the MW3 & Warzone Critical Countdown event start? 

The MW3 and Warzone Critical Countdown event began on May 29, 2024, and will be active until June 20. This gives players a solid three weeks to get every reward in the event.
