Puzzle Quest 2. Well, come on in, buddy! You've finally been invited to the party.
IGN reports that Sony's handheld will indeed receive a port of Puzzle Quest 2, launching "towards the end of 2010." Oddly enough, the IGN piece mentions the game will be available for download via PSN and makes no mention of a UMD release. We've gone ahead and contacted the game's publisher, D3, for clarification.
Along with extreme tardiness, the PSP port brings with it a new game mode called Elite. Here, the difficulty of enemies has been ramped up, naturally yielding better rewards for players and more chances to throw your PSP to the ground in frustration.
