How to unlock the ISO Hemlock in Warzone 2 & Modern Warfare 2 Season 4

There are no challenges required to unlock the ISO 45. The only way to procure this high fire rate SMG is to unlock it via the Modern Warfare 2 and Warzone 2 Season 4 Battle Pass.

If you’re wanting to plot out your path accordingly to acquire the weapon quicker, the ISO Hemlock can be found in Sector D19 and is a free unlock for all players.

If you’re new to this year’s CoD games, the Battle Pass for Modern Warfare 2 and Warzone 2 has undergone some serious changes to give players a lot more freedom in how they approach their goodies.

Instead of being one linear unlock path, the pass is now divided up into Sectors, allowing players to have more say in which items they want to acquire.
