The EM2 AR and TEC-9 SMG arrived in Season 5 of Call of Duty: Warzone. Players were able to unlock them by progressing through the Season 5 Battle Pass. You can now unlock the Assault Rifle India and Submachine Gun Kilo by completing weapon challenges in Warzone and Black Ops Cold War.
Unlock Tec-9 in Warzone
Unlock Challenge — Get 2 headshot kills using an SMG in 15 different completed matches.
You need to complete the match if you're unlocking the Tec 9 in Cold War Multiplayer. In Warzone, start a Plunder match and complete the mission. You can leave the Plunder match once the progress is made.
The Tec-9 SMG is well balanced in Warzone. It gets a massive fire-rate boost once the Full-Auto Repeater muzzle is attached. You can pair this weapon with a long range AR or a Sniper Rifle of choice.
Unlock EM2 in Warzone
Unlock Challenge — Get 2 rapid kills using an AR in 15 different completed matches.
Similar to the last challenge, you can leave the match in Plunder but not in BOCW Multiplayer.
Even after the nerf, you can easily control the EM2 AR once you get used to the recoil pattern. It has some of the best damage outputs in the game. You can rock it as a long-range AR or a sniper support gun.
