Focus is a gameplay mechanic in Marvel's Spider-Man. It is a gauge that is built by successfully landing melee attacks and dodges, and builds quicker by performing combos. As Spider-Man's Focus increases, the damage dealt by attacks also increases. Focus can also be expended to heal Spider-Man using . Additional Focus bars are unlocked upon leveling up, with the second Focus bar being unlocked at level 10.
With a full Focus gauge, Spider-Man can perform a Finisher on enemies by pressing + against an enemy. This can make battles easier by rapidly taking out certain targets, and is best used against more powerful foes, such as brutes and enemies with riot shields. In many cases, Finishers are required as bonus objectives in citywide activities.
The Skill Tree also grants abilities that improve the rate Focus builds, and allow more Finishers to be performed.
