Use the Mantle Jump mechanic by approaching a ledge and pressing the jump button again near the top edge
Sprint toward the ledge before jumping to gain enough momentum
Aim your crosshair slightly above the ledge while moving forward
Hold forward movement as you reach the edge
Practice on low walls and boxes first
Use legends with movement abilities to reach higher ledges more easily
Enable auto-sprint if available in your settings
Adjust your sensitivity if you struggle with precise ledge timing
Time the second jump just before your character reaches the top of the obstacle
If you mean mantle in Apex Legends, use jump plus forward movement near climbable surfaces
