The Warzone 2 and Modern Warfare 2 Battle Pass offers a new way to progress in the game as you 'travel' around a map, unlocking items and rewards but buying territories. It sounds unusual but it's not that different from Fortnite's approach, giving you some agency in what you want to spend your XP on.

If you're looking to make an impact, you'll want to get your hands on the best Warzone 2 M4 loadout in Modern Warfare 2. The assault rifle has already been positioned as a key weapon in MW2, mainly as every player has access to it, and the wide range of attachments available for it. The M4 is powerful and versatile, so we've made a multi-purpose aggressive and more long-range option that can help you stay competitive in the 6v6 multiplayer and larger Ground War configurations.

If you'd like to try out some different options beyond the M4, we've also got suggested loadouts for the following guns:

If you're looking to play and communicate with friends on different platforms, you'll want to get Modern Warfare 2 crossplay set up. It's really easy to do this year, however what's a little tougher is the ability to disable the functionality – while PlayStation users can tweak this, altering the pool of players they are encountering online, Xbox and PC owners may be disappointed to learn that crossplay is mandatory. If you'd rather team up locally then Modern Warfare 2 splitscreen is available, though there are only specific multiplayer modes you can use it for.

How to Access Vault Edition content

The Modern Warfare 2 Vault Edition release included the Season One Battle Pass, 50 tier skips, as well as unique weapon skins and operators. However, some players are finding that they can't access any of the content. If that has happened to you, don't panic – there's an easy fix! Here's how you can access the Modern Warfare 2 Vault Edition content if it isn't showing up.

The Modern Warfare 2 Hardcore mode hasn't arrived just yet, but it is on the way. Hardcore, now known as Tier 1, is arriving at the same time as the Battle Pass on November 16. You can technically try the mode with friends by creating a private match, however it won't be available in the general matchmaking pool until we get to that release date.

If you're looking to complete some of the weapon mastery challenges, you may be wondering: what is ADS in Modern Warfare 2? This is an acronym used in many shooters, and a potentially confusing bit of shorthand found all throughout the menus if you're new to the genre! It means you'll want to 'Aim Down Sight', rather than fire from the hip. 

Where is your KD ratio

If you want to see how you're performing in multiplayer, then one of the most widely used measures is to check your Modern Warfare 2 KD. Unfortunately, it seems that the only read you can currently get on this is via the scoreboard at the end of a match, and there's no way at present to see your lifetime KD ratio.

Modern Warfare 2 raids are coming soon
