MW4 quick help

In MW4 Multiplayer, Tactical Sprint requires Blood Rush in Perk slot 2. The launch notes say the default Sprint input triggers Tactical Sprint with this perk, when stamina allows.

1. Check that Blood Rush is equipped on the class you are actually using.
2. Check Movement Advanced Settings for your preferred Tactical Sprint input. The launch notes list single-tap run, double-tap and single-tap sprint options.

Create-a-Class unlocks at Player Level 4 in the MW4 launch notes. Use Default Loadouts before that level. A class notebook stores your ideas; it cannot unlock equipment in the game.

1. Check your Player Level in the game.
2. If you have reached the stated level but the feature remains locked, consult current official support or patch notes. This page cannot inspect your account.

The official MW4 DMZ FOB briefing unlocks the 3D Printer at DMZ Level 2. The six initial recipes in our calculator come from that briefing.

1. Check DMZ Level, rather than assuming it is the same as Multiplayer Player Level.
2. Extract the required materials intact. Check the recipe and your current unlocks in the game before planning a craft.

The FOB briefing describes recipe unlocks through DMZ levels, Orders and recipes found in the world and extracted intact. Owning materials alone does not establish that a recipe is unlocked.

1. Read the recipe’s unlock condition in your current game.
2. For an extracted recipe or resource, confirm that it reached your FOB. We do not infer unlocks or stock from your account.
