Season 5 of Call of Duty: Modern Warfare is aiming to be the biggest one yet. Not only are Warzone fans finally seeing major map changes including being able to go into the Stadium for the first time, but a massive freight train is actively moving around Verdansk and can be captured by fireteams.

In addition to Warzone features, the highly popular multiplayer has also been given new content in the form of game modes like Bare Bones as well as additional maps to fight it out on. Livestock is a brand new Gunfight map, while Petrov Oil Rig and Suldal Harbor are more traditional style maps designed for standard 6v6 matches. In an interesting touch, Suldal Harbor is actually a remake of the original Harbor map which debuted in the very first Call of Duty back in 2003.

Naturally, Season 5 also brings with it a new season pass for Call of Duty: Modern Warfare players including new cosmetic items, skins, and two new weapons. Here's more information on the ISO SMG and how to unlock it.

ISO Unlock Requirements

As expected, the ISO SMG is available for free to all Call of Duty: Modern Warfare players whether or not they purchase the season 5 battle pass. The ISO is set at tier 15 while the other free gun, An-94 assault rifle, is set at tier level 31. To unlock both weapons, simply level up the battle pass to those specific tiers.

Alternatively, players could always opt to speed up the process buy using the premium currency known as CoD Points to essentially purchase specific tiers, though the higher the level, the more money it's going to cost. Activision is offering a Battle Pass Bundle, which not only unlocks the season 5 Battle Pass but the first 20 tiers as well. That would unlock the ISO and put players in a better position to get to the RN-94. For those who don't mind spending some real world cash, the entire Battle Pass can be unlocked for around $150 USD, giving the player everything season 5 has to offer right away.

ISO SMG Details

According to Infinity Ward, the thing that makes the ISO SMG stand out from other guns is its extremely high rate of fire. In addition, the weapon has a higher rate of control and mobility than many other weapons. As such, it excels at close range and benefits those who enjoy running and gunning.

Call of Duty: Warzone is available for PC, PS4, and Xbox One.
