After defeating their own world, they began traveling from dimension to dimension, taking them over, and collecting up a rare mineral called Isotope-8, which is what they use to create their dimensional portals. That means there are 5 versions of Green Goblin, Vulture, Electro, Sandman, and Doctor Octopus. It turns out this army is lead by the Sinister Six who managed to conquer their home world by gathering multiple versions of the members from different dimensions. The basic premise of Spider-Man Unlimited is that a dimensional portal has opened up and an advanced army has invaded. A tie-in with the 2017 film of the same name, Homecoming was developed by Adrenaline Amusements solely for Dave & Buster's locations and features an incredibly simple premise (as two versions of Spider-Man pursue The Vulture) and controls (which only use one button for quick-time events). The game also received an arcade version on June 2017 as the videmption game Spider-Man: Homecoming (or Marvel Spider-Man: Homecoming). Spider-Man Unlimited (also known as Marvel Spider-Man Unlimited) was a free-to-play superhero behind-the-back endless-runner action game developed and released by Gameloft for iOS, Android, and Windows Phone on September 10, 2014.
