I absolutely want the dress Ciel wears.
Her name is Ion (full name: Ionasal.kkll.Preciel).
The official opening has been put on Youtube.
And interestingly, Earth shows up for a second at one point, and maybe shows up once or twice otherwise. You can see Africa and South America clearly. I'm really curious what that's about.
Although it might be something dumb like we silenced our world.
It's because there's active contact with our world and dimension in both Ciel nosurge and here: the people of that world call their own world "Ciel", while they call ours "Earthes", as it can be seen in the BIOS-startup screen at the beginning of the opening video. And it happens to be that the robot is called "EARTHES" too, so the most commonly believed theory is that EARTHES is actually an avatar for the player due to being the terminal the player used to communicate with Ion in Ciel nosurge being remodeled by her into the robot we see here.
And there's a lot of things the English news outlets haven't said: Ciel nosurge and Ar nosurge are prequels to Ar tonelico, the pre-Grathnode Inferia First Tower of Ar tonelico is an area the players will be able to visit (and it'll include three pieces of remixed BGMs from the first Ar tonelico: Green Lands, AT Inside ~Anomaly~ and Ancient Memories) alongside the never-seen before regions of Syestine and the Forest of Shelanoir in Ar Ciel.
As for the combat system, it'll be based off AT2's but the players will fight all encounters that can appear in the map at once: all enemies will appear in waves, and the player will be given a turn limit. If the time ends, the player will be returned to the map and given rewards (EXP, DP, money, dropped items) depending on the amount and types of monsters they manage to kill, as well as them being discounted from the encounter gauge, but the clincher is this: if the player manages to kill all enemy waves before the turn limit runs out, aside of getting the rewards, the encounter gauge will get completely emptied upon returning to the map, so this is pretty much an improvement on the standard encounter gauge system of the Ar tonelico games. And I must add that Song Magic gains the ability to blast through all waves when the player has charged it for enough time if anyone believes that they'll be severely pressed for time during battle.
Finally, Gust put out a 11-minute long gameplay sampler video
, and a Genometric Concert sampler video
. They also have plans to put up a video showcasing the music box that will come as part of the game's JP collector's edition.
