Two more games heading to iPhone and iPad have opened up for registrations before they launch, with Ubisoft's 'Might & Magic: Elemental Guardians' reviving the RPG franchise in May, while the developers of 'Ark: Survival Evolved' are accepting sign-ups for iOS beta testing.

Ubisoft has commenced pre-registrations for "Might & Magic: Elemental Guardians," a free-to-play mobile role-playing game based on the long-running game series. The new game is said to offer "fast-paced strategic battles" with "Western anime style" graphics.

As players progress through the game, they can collect hundreds of creatures, evolving them and building the ideal team of elemental warriors for combat. A single-player campaign will help with assembling the team, along with a competitive PvP mode allowing players to take each other on in online battles.

While Ubisoft says the game is a "fresh take" on the original, it will still feature some of the characters previously featured in the franchise. Set in the world of Ashan, it will take players to new areas unexplored in previous games, which will apparently provide some familiarity to existing fans of the series, while still making sure new players will be able to take part without needing to know about the lore from earlier releases.

"Might & Magic: Elemental Guardians" is currently being soft-launched in Canada, Australia, the Philippines, Singapore, Denmark, Norway, and Sweden, with the worldwide launch slated for May 31. Those pre-registering for the game will receive an in-game reward of a "very specific creature" that will unlock when the game ships.

Studio Wildcard is working with War Drum Studios to port the popular survival sandbox game "Ark: Survival Evolved" to iPhone and iPad. Arriving sometime this spring, the developers are opening up the mobile version to the public in an iOS beta test, requesting interested players to sign up for the trial.

Based in a Jurassic-era world, players find themselves stranded on a mysterious island without tools or resources. To survive, players have to build shelters and hunt for food, improving their living situation and working with other players in tribes.

Aside from interacting with up to 50 players on a server, players will also need to take on the assorted dinosaurs also populating the island. Over 80 species of dinosaur roam the land, which can be tamed and trained for riding, bred with others, and used to attack rival tribes.

The graphically intensive game will need an iPhone 7 or later to run, according to the official Twitter account, and will take up 2 gigabytes of storage. Compatibility with iPads has not been confirmed, but it is advised the game will require 2 gigabytes of RAM to run on iOS, while the Android version will need 3 gigabytes of memory on devices.
