The Mobility Course in the Modern Warfare 4 beta is a proper test of nerve. It sits inside the Proving Grounds and throws movement, shooting, and quick decisions at you all at once. If you are chasing the Clockwork Weapon Charm, the Expert route deserves more than a quick attempt, and a look at MW4 Bot Lobbies may help you warm up before taking on the timed run. The required result is an S-Tier finish below 56 seconds. A 58-second run simply will not be enough.

Plan the Route Around Targets

Speed matters, but it is not the whole story. Each target you hit removes one second from the recorded time, so a slightly longer path can be faster in practice. You will often spot extra targets below the main walkway or just beyond an obvious jump. Take those detours when they are safe. Dropping down a level can pay off, but a missed landing or a laser trap will wipe out the time you hoped to save. The best runs feel controlled rather than frantic. Keep moving, yet give yourself enough room to land cleanly and line up each shot.

Settings That Keep You Moving

A few controller changes make the course easier to read. Lower thumbstick sensitivity a little if your aim tends to drift while sprinting. Tactical Sprint Assist is useful on straight sections, where holding forward should keep your pace high. Tap to Slide works well for most players, while the hybrid option remains fine if you already use it without hesitation. Toggle sprint behaviour can make movement feel less tiring, and Double Tap for Tactical Sprint Activation helps stop unwanted bursts. For the water sections, set Plunging Underwater to Free so you can choose when to go below the surface.

Use the combat knife whenever no target is nearby.
Reload during quiet gaps between target groups.
Watch for lower platforms with extra targets.
Leave room for safe landings near traps and drops.

Build Confidence Before Expert

Do not rush straight into the hardest version. Beginner and Intermediate use the same basic layout, although Expert stretches the route and gives you less room for mistakes. Those earlier attempts are ideal for learning target positions, jump timings, and the points where a reload fits naturally. During shooting sections, use the pistol and keep your crosshair ready. When the course gives you a clear run with no targets, switch to the knife for its faster movement. It is a small advantage, but several small gains can turn a near miss into a qualifying run.

Make the Run Feel Repeatable

Record your first few attempts mentally: where did you lose time, miss a target, or arrive with an empty magazine? Fix one problem at a time instead of changing everything after every run. Once the route feels familiar, focus on smooth transitions between sprinting, sliding, aiming, and reloading. That rhythm is what carries you under the target. When the Clockwork Weapon Charm is finally within reach, a few practice sessions using cheap MW4 Bot Lobbies can help you settle your aim before returning to the Proving Grounds, where patience matters as much as raw speed.
