Call of Duty: Modern Warfare 3 Zombies and Multiplayer Guide

Modern Warfare 3 splits your time between traditional multiplayer and open-world Zombies, and treating them as separate grinds instead of one combined one saves a lot of wasted hours.

Use Zombies for weapon leveling, not just loot

Zombies contracts are a low-pressure way to rack up weapon XP toward camo challenges that are painful to chase in competitive multiplayer lobbies. Save the harder headshot- or longshot-specific camos for Zombies runs where you control the pace.

Don’t skip the multiplayer map callouts

Several maps are reworked versions of older ones, and assuming you already know every angle is a common way to get caught out. Spend a few games just rotating and learning sightlines before pushing for kills on an unfamiliar layout.

Between two progression systems competing for your time, a booster handling the camo or rank grind in one mode frees you up to actually enjoy the other.
