The Symbiote

The symbiote suit sections are Spider-Man 2's best gameplay. The power spike is real and intentional, you're supposed to feel unstoppable, and you do. The combat opens up significantly, enemy encounters become violent spectacles, and the visual design of the dark suit is exceptional. What makes it work as story is the cost. Peter's behaviour changes in ways the game doesn't comment on directly, you notice it in how he talks to Miles, how he rationalises the aggression. The player feels the appeal before the story reveals the problem. That's smart writing. It just needed the back half to match the setup.

Faster Than Ever

The original Spider-Man had fast travel that involved an actual loading screen. Spider-Man 2's fast travel takes less than two seconds and leaves you wondering why they included it at all given how fast you can get anywhere on the Web Wings. The map expansion into Brooklyn and Queens means there's more city to actually traverse, and Insomniac tuned the building heights and street widths in the new boroughs to support the increased speed. The slingshot launch mechanic, webbing between two anchor points and releasing to rocket forward, is a new tool that rewards the same physics intuition the first game built.
