Upon hearing the news that Spider-Man 2099 was the third of four playable "dimensions", fans of the books and games scratched their heads in confusion and anticipation as to what the last costume could be. Assumptions ranged from "Spider-man Reign" to "Spider-man India". Cosmic Spidey was also mentionned but this one we don't have to worry about anymore since he will be the exclusive costume for pre-ordering the game! So that's one down... what other "in game" bonuses to come might slim down the alternatives?
For the last of the four suits, my money is on a Spider-man that has never been Peter or crossed Peter Parker's path yet so i'd scratch Scarlet Spider or even Civil War Spider-man off the list, personally. They might pop up as bonus costumes to use but i doubt they'd get their own playable dimension. Lets list all the possibilities left in the comments section!
