A few levels have secondary objectives, which are not required to complete unless on the normal or hard difficulty setting.

Those who survived this dramatic training would never be able to take the normal difficulties of normal life seriously.

There are three difficulties: easy, normal, or hard.

In order to reach the extra stage, one must beat the game on normal difficulty or higher without the use of a continue.

I finished all of the above sp games (one notch above normal difficulty) in 5 hours or so.

People with AS have normal to high intelligence but great difficulty with social behavior.

It took me about 14 hours of solid play to get through the single-player story in Uncharted 2 on normal difficulty.

Players can choose between easy, normal, and hard difficulties.

Elite mode is designed to be harder than normal difficulty with several adjustments to game mechanics.

It took just 10 days of sporadic play to complete the 14 missions at the normal difficulty setting.
