This is one of the best games I have played in a very long time! The story is you are a hero drawn to a kingdom being consumed by an evil fog bringing demons to plague the lands. You choose from different classes that basically mean nothing since everyone can use any weapon and max all your stats. Your choices are heavy melee like a knight, rouge like quick melee, melee caster hybrid, dark magic, or holy magic. You die shortly into the game and are introduced to the death cycle in the game. This is something you will get very used to because you are going to die, and die, and die, and die, and die again, over and over again. The game has a sharp difficulty curve and even if you have played it and expect what is coming you can still die from a simple mistake.
You can summon the help of up to 2 other players to fight with you against all evil. Once you defeat a boss your helper gets resurrected and goes back to their home world. There is also red phantoms, these are not friendly. They will hunt you down to try to kill you. These human players are worth a lot of souls, the currency of the game. The last multiplayer aspect is world tendency. When online the tendency will be grey which is in the middle. When you die, it shifts to dark. When you kill a boss or big demon it will shift to white. White worlds are easier, but you don't get great prizes. Black worlds are more difficult. Stronger red demons appear, that would not normally, but it is easier to find treasure.
The game is unforgiving, yet very rewarding. You will die a lot, but it is never unfair. When you die, it is because you made a mistake. You must learn from your mistakes. For example, charging up the stairs only to be impaled by a demon knight that is lurking around the corner . When you come back he will be in the exact same spot, so be prepared. Monsters do not hunt you down, so you can take your time. This is my favorite PS3 game.
This game is well worth the money and frustration. I give it a 10 out of 10!!
