Unlock requirements are rarely stated plainly in-game, which is why how to unlock dead ops arcade bo1 gets searched so often. Below is the actual condition, plus the fastest way to satisfy it.
The community figured most of this out through repetition, and the pattern has held up well. Most advice on this topic assumes you already know half the answer, which is exactly the problem. If something here stops matching what you see on screen, the game has probably changed a value in an update.
The short answer
The unlock fires on a specific condition rather than on progress in general, so aim directly at that condition instead of playing more.
If the unlock does not appear
The approach below has been checked against the current version rather than a patch from two years ago. People often blame the game when the actual cause is a setting they changed weeks ago. If something here stops matching what you see on screen, the game has probably changed a value in an update. One clean run beats five rushed ones, both for results and for your patience.
Nothing below requires mods, paid tools or an account on some sketchy site. Anything marked optional really is optional, so skip it without guilt. The difference between a smooth run and a frustrating one usually comes down to preparation, not skill.
