while the time limit is good for a challenge, there definitely needs to be an extended play mode (ie zen mode) with no time limit. also there could be tons of achievements put in, which everyone seems to love. 5/5 anyway, nice fun polished game.
4/5, good job, but randomly turning around is retarded. the guards actually move like real guards when they're on Alarm mode, but when they are just patrollling, who the fk randomly turns around 3-4 times while walking a path? a lot of times there is no place to "stay patient" at, and you end up being forced to go invis hopefully they will randomly turn away for long enough so you can move, but they dont and you run out and they kill you. not enough hiding places, too much luck.
