3 hours (around 6-7 if you complete all achievements on a second run) of interesting puzzles and eerie atmosphere. first/thirdperson modes come with both up/downsides, so you see yourself switching between them pretty frequently (eg. rabbit is harder to spot in first person, aiming is easier, overall movement is harder in thirdperson).
if you got the money to spare be sure to check it out!!

one of the best in the series, it just offers so much!!

its a football game, dont really need more after that
