Starting in October 2014, Gameloft released several updates that added chapters to the story mode, Spider-Men and Spider-Women, enemies, events, and stages.

Reviewers praised the game's controls, sound, animation and the variety of characters, while criticizing its energy system, which they considered a limit to its playability.

[11] By completing missions, the player can win experience points to reach the next level and in-game currency: regular vials or rarer ISO-8.

[16] Additionally, players can complete extra missions called "Spidey Ops", in which one or more characters, up to a maximum of six, become unavailable for a set period of time; when they return they gain experience and vials.

[17] Its soundtrack was composed by Pascal Dion, and it was directed by Baptiste Marmey, produced by Steve Melanson, designed by Corentin Delprat, and programmed by Jerome Chen.

[18] At a press release on June 6, 2014, Gameloft announced it had formed a partnership with Marvel Entertainment and was developing a Spider-Man-based game for smartphones and tablets.

To create an endless runner that would differentiate itself from others in the genre, the staff focused on Spider-Man's main powers, which originally led to a swinger-only game.

After the narrative designer creates the main plotline and dialogues, they consult Marvel writer Fred Van Lente for feedback.

[24] Characters were designed to be balanced and, with this in mind, the production team tried to implement similar abilities for the Spider-Men and Spider-Women, despite giving them different skills.

Requests on their forums, Facebook page, subreddit, and Twitch were also considered, but they always focused on thematic releases; for example, "Monster Spiders" (Spider-X and Tarantula)[28] or dimensional variations of Spider-Man.

[30] The main villains of this storyline, the Inheritors, were faced in the "Great Hunt" event; first Karn and Morlun,[26][31] then Daemos and Jennix,[11][32] and ultimately Solus.

[15] The eighth, released in October, continued Spider-Island, and added Renew Your Vows character Annie Parker and costumes from the All-New, All-Different storyline.

[25][41][42][43] Other common update content included thematic fights against specific villains, such as Jack O'Lantern,[25] Hydro-Man,[26] and Silver Sable.

The 32nd update of the game also featured the release of the Iron Spider based on the movie incarnation as well as the introduction of other characters, particularly those from the Venomverse story.

[3][50] Squires and Musgrave praised the variability between running, swinging, climbing and free-falling; the former stated, "the result is a game that continues to feel fresh long after the hundredth play".

[7] Musgrave commented, "the art style does sometimes hinder the gameplay",[1] and Willington was critical of the story mode, which he said had a "weak plot" and lacked character development.

[7] However, according to Musgrave, the game's energy system was "the biggest point of controversy";[1] he, Willington, Allen, and Mike Fahey of Kotaku criticized it.

[5][8][12] In opposition, McElroy said the energy system is a "microtransaction hook" that is easily surmountable without spending any real money,[3] and Squires affirmed that because of the duration of a run it "ends up feeling a lot fairer in practice than it sounds on paper".

[7] While David Chapman of Common Sense Media generally praised the game, saying it "does a great job of capturing the feel of the comic books", he was critical of its frequent adverstising and pop-ups that contributed to what he described as an "ever-present push to buy something".

[51] When Gameloft announced Spider-Man Unlimited would be discontinued, Ryan Winslett of CinemaBlend and Tyler Fischer of ComicBook.com noted that fans would be disappointed as the game's plot was not concluded, resulting on a cliffhanger.

[48][49] However, Fischer noted some fans were already expecting it,[49] while Winslett stated it is not rare for a mobile game to be shut down without any previous announcement, which made the three-month warning sound good.
