A few useful answers.
Game versions, source checks and what the tools can actually do.
Which version of DMZ does this site cover?
The current guide path covers MW4 DMZ in Hajin. Legacy Warzone DMZ is a different ruleset; identify your game before following a guide.
Where should I start with MW4 Multiplayer?
Use the first-match checklist to set a control baseline, check your current class options and choose one match objective.
Do the tools connect to my Activision account?
No. Plans, builds and match totals are entered manually. The tools cannot read your game inventory, validate attachments or retrieve account statistics.
Where do my plans and class notes go?
The deployment planner and class notebook save in this browser on this device. Export JSON downloads a copy. There is no import screen, account sync or cloud backup in this edition.
Are these official Call of Duty guides?
No. This is an independent publication. Articles link to official sources, distinguish creator observations and show the date of their substantive review.
Can I use the site without an account?
Yes. Reading and the three tools require no sign-in. JavaScript is required to calculate, save or export tool data; the guide text remains available without it.
