Takes a few hours to understand the gameplay mechanics, but once you catch on this game is a lot of fun.
The gameplay mechanics are something relatively new. Each of the seven members has a unique weapon and supernatural power. So supernatural, that in fact, they would have been burned in the witch hunts. Some of the characters are significantly more powerful than others, but they all can be played with ease. Some tasks require the use of a particular character's abilities. Such as telekinesis or freezing an enemy in time. When your teammates receive a certain amount of damage, they will collapse and you are faced with an option. To revive them and risk your own life, or to leave them to die and save yourself. But when your teammates faint, and you're the only person left, you'll wish you had revived them. Some battles can end up being you vs. 100 enemies. And the enemies don't die easily.
The environments work well in this game. They are very creepy, dark, and the music and sound effects seem to fit well. The enemies are all look very frightening, but are over-used and repeated. The levels are rather large, and fairly linear. There are a few turns that lead to dead-ends, but a lot of searching isn't required. The graphics are fairly good as of 2007 standards. They definitely aren't PS2 quality, like others have stated. But they still could be a little better. The cutscenes are all very intriguing. They aren't too long, nor too short, and they all contribute significantly to the story.
Overall, Clive Barker's Jericho is a fun game. It's definitely not one of the best games I've played on the PS3, but has quickly become one of my favorites. Even though there are some flaws, and the gameplay can be frustrating and boring at times, it is still a game that I can't put down for more than 30 minutes at a time. This is a must-have for anyone of the survival-horror genre, because this one nails it. Dark environments, creepy enemies, limited ammunition, and a frightening soundtrack. Jericho really delivers.
There is also a petition to make a sequel.
