Peter Parker, at 15 years old, was bitten by a genetically modified spider, and as a result, he developed superhuman abilities after the bite, including enhanced speed, strength, and agility, as well as the ability to cling to vertical surfaces like a spider. Peter transforms into Spider-Man once he dons the mask, web shooters, and suit. Peter has known Eddie Brock Jr. since they were children. Eddie was looking for the scientific heritage left by his father when he came into contact with a symbiotic suit that altered his appearance and turned him into the monstrous Venom. Ultimate Spider-Man follows both of their adventures that were scripted by Brian Michael Bendis. In Ultimate Spider-Man, Spider-Man tries to stop Venom from killing innocent people, while Venom tries to avoid being manipulated by S.H.I.E.L.D.’s schemes.
The Ultimate version of the Spider-Man mythos reimagines the series by introducing edgier (and frequently younger) iterations of well-known heroes and villains from the Marvel universe. Some of the Ultimate characters that make an appearance in this game are the Human Torch, Wolverine, Electro, and the Green Goblin. The game Ultimate Spider-Man offers a fully drawn and cel-shaded version of Manhattan that may be explored.
Spider-Man and Venom may, with very few exclusions, move freely around Manhattan and Queens, climbing buildings, leaping between rooftops, and swinging from webs. On the map, story missions and other types of in-game objectives appear as hot spots in the same way. After the player has finished exploring the city (or destroying it), they can proceed with the tale by visiting these key locations. Spider-Man and Venom have the option, in the time between plot missions, to participate in other side activities such as races, go on military tours, find secret icons and collect them, and assist or hinder the inhabitants of New York.
