Gameloft, most recently of the Dark Knight Rises tie-in fame, have recently been promising their first mobile game using Unreal 3. That game is Wild Blood, and this is its trailer.
By itself, without context, this trailer might not be terribly impressive. These are elements we've seen before, after all. Giant sword, ominous castle, goblin-creatures... but to see mobile games using the same Unreal Engine 3 that console and desktop games use? That's a trend I can get behind.
