Let's start with special tools for installing mods.
Spider-Man PC Modding Tool - allows you to extract and replace any asset in the game's asset archives. It's the foundation of creating and installing mods, having an easy to use mod file system where users can create and share their mods, and also install them.

Another special tool for installing mods
Adding Suits to New Slots Tool - Instead of replacing existing suits, this tool allows to add suits to new slots for compatible mods.

Surely many of us were disappointed not to see one of his best incarnations among the many costumes of Spider-Man. This mod does not replace costumes from previously created ones, but adds a separate slot.
Modeled closely to the live action suit and edited the proportions to match the build of Andrew's Spider-Man while staying functional for the game's rigging.

Tango's Mayday Bundle - mod that adds a pack of costumes from the line of comics about Spider-Girl, Peter Parker's daughter. This line of comics is one of my favorites in the history of Spidey so I decided to share this mod with you

I love this mod! Without it, a replay cannot be possible! The new combat animations are amazing I can't describe it in words you have to see it for yourself
EXPRESSIVE COMBAT is a combat and finishers animation overhaul that changes ground combos, combo intros, combo enders, air combos, air combo enders, wall combo enders, ground finishers and air finishers to fit a more fast and aggressive style

To finally refresh the gameplay, just install this mod. New flight, stunt and free fall animations
EXPRESSIVE ANIMATIONS acts as an addon to other animation mods to breath more life and fluidity to traversal! It also introduces a new traversal mechanic called Web Dash.
