How To Unlock ISO 45 SMG in Modern Warfare 2 and Warzone 2

Warzone 2 and Modern Warfare 2 Season 4 is here, and it brings four new weapons for players to try out. One of them is the ISO 45 SMG, a returning weapon from Modern Warfare 2019 and the original Warzone.

The ISO 45 SMG is a lightweight and compact SMG that fires .45 Auto rounds. It has a high fire rate and decent damage per bullet, making it ideal for short- to mid-range engagements. However, it also has high recoil and low magazine capacity, so you have to be accurate and reload often.

If you want to get your hands on this fast-firing SMG, here’s how to unlock it in Warzone 2.

How to unlock ISO 45 in Warzone 2 Season 4 Battle Pass

The ISO 45 SMG is part of the Season 4 Battle Pass, which means you can unlock it for free without spending any money. However, you will need to earn enough tokens to invest in the sector where the weapon is located.

The ISO 45 is the High Value Target (HVT) of Sector D19, which means you have to complete all four rewards in that sector before you can claim the weapon. You can earn tokens by playing Warzone 2 or Modern Warfare 2 matches, completing challenges, or buying them with COD Points.

Once you have enough tokens, you can go to the Battle Pass menu and select Sector D19. You will see the four rewards that you have to unlock first, which are:

• A calling card
• A weapon charm
• A sticker
• A spray

After you unlock these rewards, you can use one more token to unlock the ISO 45 SMG. The weapon will be added to your loadout menu and you can use it in both Warzone 2 and Modern Warfare 2.

The ISO 45 is similar to the old ISO from Modern Warfare 2019 and the original Warzone, but it has some differences in stats and attachments. For example, the ISO 45 has a lower fire rate but higher damage than the old ISO. It also has different barrels, stocks, and magazines that affect its performance.
