How to unlock the ISO Hemlock in Modern Warfare 2, Warzone 2

One of five new weapons that joined Call of Duty: Modern Warfare 2 and Warzone 2 in season two is eerily reminiscent of one of the best guns in the history of the franchise.

Anyone who played the original MW2 back in 2009 knows all about the ACR. That gun was dominant in its power, feel, and general ability to dominate lobbies, no matter what attachments it used. A new assault rifle in season two, the ISO Hemlock, has the ACR’s vibes written all over it.

“A powerful and enhanced rifle from Expedite Firearms is designed to take both 5.56 and subsonic .300 BLK ammunition, providing battlefield-advantage in any situation,” Activision said of season two’s new AR.

Since it was added to the game, it instantly became one of the favorite weapons of players in both MW2 and Warzone 2. It’s so powerful, it even got banned from ranked play mode in MW2. It’s still a favorite months later.

Before you can use the ISO Hemlock in MW2 or Warzone 2, it needs to be unlocked. That’s when the real fun begins and players can level the weapon up to help it evolve into the beast it can be in the Gunsmith.

Here’s how to unlock season two’s assault rifle in CoD.

How to unlock the ISO Hemlock in MW2 and Warzone 2

The ISO Hemlock was free to unlock as part of the season two battle pass in MW2 and Warzone 2. Players only needed to play through the season, obtain unlock tokens, and use them on the battle pass track to unlock the weapon to use in any of CoD’s modes.

Now that season two has come and gone, however, there’s a simple in-game challenge to unlock the weapon so you can use it in your matches. It’s still free to unlock, but you’ll need to work a bit to get it into your arsenal in CoD.

Here’s what you need to do to unlock it:

• Get 20 Longshot kills with Assault Rifles.
• Extract the ISO Hemlock successfully in DMZ.

Once you’ve completed one of the above requirements, the ISO Hemlock can be found within your collection of weapons in MW2, Warzone 2, and DMZ.
