Fun for four people, or decent solo as well.
The game starts with the execution of a death row inmate. Only, it doesn't go as planned, and for some reason unleashes evil spirits onto the people who are in the prison, and all of the dead inmates from the past come to life. The 4 protagonists lock up the prison so the evil can be trapped inside. And it stays that way until some annoying rave kids have a rave party there, and get what they deserve... That's where the game starts.
Up to four players can play as one of the four characters simultaneously. Each of the characters have their own strengths and weaknesses, and their attributes increase as you gain experience, although it's not really noticeable. The game is basically running through different areas, hacking and slashing zombies, with a few extra goals thrown in.
The gameplay is good. The left thumbstick moves the character, and the right one changes the direction of the characther, so you can run and attack in different directions. The difficulty level was perfect, there were a TON of enemies, definitely enough to create a challenge, however, with some careful playing it's not too difficult to complete the game. The graphics were also good. I played this game solo, and it was decent. It's even better if you play multiplayer, it has an arcade game feel to it, with some RPG elements thrown in.
