New Turtles and Iron Man 3 apps have been released.
Nickelodeon has launched its first worldwide mobile app with its Teenage Mutant Ninja Turtles: Rooftop Run.
The network's new app is available in more than 150 countries and eight different languages.
Available for iPhone, iPad, and iPod touch devices, Rooftop Run will join the heroes in the runner ninja combat game set in the New York landscape.
By defeating enemies, players will earn coins that will offer character power-ups, weapons and gear.
Players can build their collection of coins to purchase in-game enhancements in the Turtle Lair or enter a password for an active iTunes account.
Meanwhile, celebrating the release of Marvel's Iron Man 3 in the UK and Ireland, Tesco has teamed up with The Walt Disney Company UK to launch the Stark Armoury App.
The new app will allow fans to gain access to the Mark II suit, take a picture of themselves and then share via social media.
Users can unlock further features by visiting Tesco stores and scanning selected stark Armoury labelled displays.
The features include six different suits, multiple weapons and a feature that allows the user to see a fully 3D Iron Man on screen.
Users can also access features of the App at the Tesco Iron Man 3 website, http://www.tesco.com/direct/ironman/
Matt Entwistle, Tesco general merchandise marketing director, said: "The Stark Armoury App is a brand new way for our customers to join in the excitement about the movie, and will add an extra bit of fun to the family shopping trip - online and in-store.
"We're delighted to be working with Disney in bringing this unique Marvel App to Iron Man fans."
Nigel Cook, vice president of Marvel International, added: "The Stark Armoury is a fantastic and engaging piece of Marvel content, and forms part of an extensive retail opportunity with Tesco that will run from now through to the DVD release and Christmas.
"Iron Man 3 is a key driver this year for the overall Avengers franchise, and the full product range will continue to be supported with TV programming on Disney XD and ITV ahead of the cinema release in November of Marvel's Thor: The Dark World."
