Marvel Puzzle Quest Dark Reign is a role-play and puzzle game in which players have to form teams with some of the most famous superheroes in Marvel Comic history, including Iron Man, Thor, Spiderman, and Wolverine, and use them to take part in intense 'Puzzle Quest' style combats.
The gameplay in Marvel Puzzle Quest Dark Reign is virtually identical to that of the original 'Puzzle Quest.' That is, you have to connect three or more of the same colored pieces on the game board. When you do that, you inflict damage on your enemies and earn energy points to pull off special moves. The different special moves you can do, depend on which hero you're playing with, of course.
As the story unfolds, you have to travel around the world facing off against all of your enemies, which are controlled by artificial intelligence. Moreover, as you win more fights, new characters become unlocked and you can add them to your ranks.
Marvel Puzzle Quest Dark Reign is an excellent addition to the puzzle genre, and it perfectly combines the Marvel atmosphere with some near perfect role play action. Also, the game is absolutely free.
