Effect: Your character is unable to move, and is an easier target.
Causes: There are several ways to become immobile, such as having two injured legs, or being knocked over by a critical hit or explosive. Also being way over the carry weight capacity can also cause immobility
Cure: The cure for immobility depends on the cause, if your character has two injured legs, using the Doctor skill to repair one of them will cure this condition, if the character was knocked over by a strong hit, then only time will help, as the character will pick themself up off the ground after a period of time. For over encumberance, drop some items or pass them to another squad-mate.
