The gameplay is very much focused on stealth based attacks be this by using the bow/arrow combo or sneaking around to perform a melee kill. I suppose twenty years after a virus outbreak ammo & supplies are going to be a bit scarce. I enjoyed luring the enemies into a trap by placing nail-bombs at corners & enticing the enemies to charge over to me. Getting a group of clickers together & treating them to a molotov cocktail is one of the most satisfying aspects of completing a difficult area.
Yes it is a linear story but when it is presented, voice-acted, played so well there is nothing wrong with linear.
