Puzzle Quest was a surprise hit for publisher D3. Likely tuning into that, D3Publisher of America has decided to purchase Vicious Cycle, the developer behind the PSP SKU of Puzzle Quest.
Vicious Cycle is the first developer acquisition by D3. In addition to Puzzle Quest, Vicious Cycle has a number of games in the works, including PSP exclusive Dead Head Fred. Previously they've developed such titles as the licensed game Flushed Away and Marvel Trading Card Game.
