Like I said before, graphically, Sanity: Aiken's Artifact
starts off looking like a turn-based RPG, but don't let the looks fool you. You are playing an action game, and action is what this game delivers. You portray Agent Cain, a psionic agent in the 21st century. During an experiment to unlock the unused portion of our brains by the use of a serum, things started to go wrong. Subjects in the experiment would start to go insane because their brains could not adapt to the new powers or 'talents'. Cain was different because he was given the serum while in the womb, so his brain was able to deal with the talents and keep his sanity longer. Able to control these talents and his sanity, Cain joined a police force formed to deal with psychotic psionics called the Department of National Psionic Control, or the DNPC. There is a lot more to the back-story and many more characters in the mix, you need to discover that on your own. You, as Agent Cain, are on a mission to control psionic criminals.
Through integrated movies, you are given your missions along the way. You will start off the first mission with the fireball talent, which I have found to be very effective. Be warned: you cannot continuously use your talents without it affecting your sanity. You will be able to keep track of your sanity and your overall health through the in game interface bar. This bar will also give you the ability to talk to headquarters amd flash your badge or gun (which you will need to do with certain characters to get the required information). You will also be able to choose which talent you will use against your foes, which range from rednecks to psionic controlled ghouls. To fight them off effectively, you must be quick and keep moving all the time. You remember the saying, 'a moving target is harder to hit'. After you have destroyed an enemy, there will sometimes be a power up vial to increase your health or sanity. Every once in a while, an enemy will leave behind a new talent. The levels, of course get more intense as you go along. There are some spots in the game that you must have talked to a certain person or have a certain talent before you can progress further in the game. Don't ask me how long it took me to get through a certain spot.
Sanity also has multi-player options for over the Internet or over a local network. The game performs the exact same way in the multi-player games, but they are geared more as deathmatch games, rather than having a storyline to follow.
