To get the other, I simply had to do the same thing again, but move the additional two squares to kill him. Not killing the final, optional guard got me one bonus objective. In one level, it was necessary for me to kill all but one guard to reach the end. This is fine when they heighten the challenge – retrieving the briefcase tends to require an extra step in your process that justifies the effort.

There are two per level, and often they're mutually exclusive. These are drawn from a standard template: retrieve the briefcase from a specific square, kill all the guards, don't kill any guards, or finish in a set number of moves.

Some additional difficulty is provided by each level's bonus objectives.
