Marvel's Spider-Man/Gadgets

Gadgets can be used by Spider-Man by pressing psx: R1, and can be cycled through by holding psx: L1 and moving psx: neutral rstick around the wheel (once others are unlocked/crafted). Upgrades for these gadgets can also be unlocked via crafting, allowing for higher capacity, range, and other advantages.

Web Shooters
Web Shooters are Spider-Man's default gadget, and while a single web shot doesn't do much damage on its own, rapid-fire web shots can severely incapacitate tough enemies (such as brutes). While enemies are able to break out of the webs eventually, when webbed up close to walls, enemies will be unable to move for the remainder of the battle. Enemies can also be thrown by holding psx: T when webbed up (after the Web Throw skill has been unlocked, which can be found at the top of the Innovator tree). This can be paired up with other skills, such as Hazard Zone (which knocks down surrounding enemies in the windup of a throw) in order to effectively deal with crowds.

While the Web Shooters become somewhat obsolete once Impact Webs and Web Bombs are unlocked, the high capacity and short recharge time of the Web Shooters make this gadget a good backup in tough situations.

Impact Web
The Impact Web lacks the high capacity of the Web Shooters, but makes up for it in strength. One shot of the Impact Web is enough to web an enemy up, taking them out for the time being. If you feel the need to pare the number of enemies down quickly, Impact Webs are a good way to do it. As with Web Shooters, it is possible to stick enemies to walls if they are hit with an Impact Web in close proximity with a wall, though this is made easier with the Impact Web's ability to knock enemies back; this is a good way to deal with brutes, as a brute can charge at Spider-Man before he has the chance to web him up with Web Shooters.

If you're looking for more crowd control, the Web Bomb may seem like the superior choice, but upgrading the Impact Web gives it the ability to spread to enemies that come into contact with the initial target, making it a viable alternative.

Spider Drone
The Spider Drone serves as a handy distraction, as it will come to Spidey's aid momentarily, shooting blasts of energy at any who come close to the hero. The Spider Drone is similar in purpose to Spider-Bro (the power assigned to the Stark Suit), though it doesn't last as long. However, there is an advantage in that multiple Spider Drones can be deployed at a time, giving Spider-Man a chance to recover against a crowd of enemies.

The Spider Drone is one of few gadgets not unlocked through story progression, instead becoming available to craft at Level 8 (with 1 Base Token and 3 Research Tokens).
