Earlier this month, Gematsu discovered a U.S. trademark from Marvelous AQL for something called Cross Horizon.
Today, Siliconera has come across a logo for the game.
Any guess as to what type of game it might be?
Update: As noted by Gematsu reader Anti, it turns out Cross Horizon is a smartphone game launched about a week ago. If you have an Android phone, give it a go.
