thanks to the greater openness of the environment and the resulting different possibilities of approach. the landscape offers numerous strategies to face the enemy, accerchiandolo, sticking his head down or quietly, with stealth killings calibrated to the millimeter. the innovations introduced here thus refer the detection-system AI enemy and Nate's ability to act through stealth movements, favored by the natural shape of the location. the battle can be divided into two simple stages: the first consists in the approach to the target, with the possibility of mark the enemies from a distance, by pushing the buttons L2 and L3; mechanical performance rather trivial in the application because of a too wide range that allows the player to activate profusely markers on enemies are not in visual range. The second, however, is the classic phase of engagement, already present in other earlier chapters, in which the user can decide how to proceed in the clash: the level design of Uncharted 4: End of a Thief in fact allows all types d ' action, emphasizing stealth attack in favor of a boarding without rules. Naughty Dog has provided in this chapter carto the slaughter of unsuspecting enemies of the presence of Drake and, in the vicinity of some contextual areas - such as evergreen shrubs borrowed from a long line of previous games, the body can be automatically hidden from view. Often the latter technique is necessary to eliminate the large number of soldiers present: their projectiles causing high damage to Nathan and throw himself openly in the battle is only recommended for experienced players. This constant urge towards a silent approach has led the Californian software house to design a detection system consisting of the three states "ignorant", "alarm" and "fighter", each determined by a specific color and by a device placed over the roar opponent's head. The system is surprisingly responsive and the look of the sentries is natural and well designed, without encountering thus casus belli generated by X-rays of a friendly guard armed named Clark Kent. Last but not least it is inevitable to mention the grappling hook, already known after the introduction trailer released in the previous months; it can be used not only to solve puzzles related to the environment but also in battle, to rappel from above on unsuspecting enemies or to move quickly on the pitch.
