while i was playing Nightfire, a James Bond series game in 2007, i was not that much old with the present time gaming as you may say just my introduction to the high end gaming then .. i was shocked with the night vision of the character i was playing with .. as by that feature, the character could see through any concrete object to detect the enemy behind and to get alerted in due time .. to me, that was pretty helpful to move ahead without getting hurt .. still remember that i enjoyed that much
