So, there's 4 main playable characters, one new one and 3 old ones, 2 of which are NPCs from the original game
There's
Zap: zap's gameplay style is more bomb rush cyberfunk and JSR like. You can glide across rails and power lines, and also do flips or other cool stunts
Dob: Dob's gameplay style involves running on walls, and using makeshift ziplines and grappling hooks
Dot: parkour, but I mean like Tony Hawk minus the skateboard. Like extreme parkour
Shot: GTA and Yakuza style gameplay, running or walking, but also involves fighting and parkour is more difficult, think of it as a challenge mode, he's also the only human in the crew (also his real name is Douglas Fenrick)
the whole thing is that a recently built spaceship crashed into earth, but during the crash, parts scattered all over the world, but the main area (nicknamed Crew HQ) was left undamaged and crashed in the middle of downtown Toronto, and the crew HQ is basically the home base, and shot just joined in because he needed a place to stay due to getting evicted, but he got tangled up in the wacky adventure due to joining the crew.
But along with traveling all over the world, you also have to defeat the mad scientist PROFESSOR HELIX! he's trying to take the entire alien species down simply to use them as a power source by extracting that'sfuckingwackium from their DNA..
