Chris is a playable character, although to get him there are many more requirements to fulfill than obtaining any other character in the game.
The steps to getting Chris are:
1. Go to the school science lab(right of front door) and talk to the teacher wearing the brown suit. He will tell you of someone going in and out of a sealed classroom on the second floor. Doing this triggers the door to room 2-7 to unlock.
2. Go to room 2-7 of the high school and see Chris acting suspicious. He will leave the room when you see him.
3. Go to room 2-1 of the high school and talk to the male student who is there. He will tell you about someone partying at the factory. The person he is talking about is Chris.
4. Go to the Joy Street mall and enter the Yin & Yan shop. Talk to the female customer wearing jeans, this is Chris' mother. She will ask you if you know her son Chris, answer Yes, you know him. She will then ask you if you will be his friend, answer OK, you'll be his friend. Leave the Yin Yan shop without talking to Chris' mother a second time. If you talk to her a second time, she will ask you if you've seen Chris yet and that will ruin your ability to get him.
5. Go to the Revolution 1999 in the Joy Street mall. Talk to Mark's two band members(standing next to Mark). They will tell you of seeing Chris at the factory.
6. Go to the factory, Chris will be there if you've done the above steps in order. When Chris sees you he will leave.
7. Proceed through the game as usual, until you are finished with the hospital(first dungeon you needed to do).
8. As soon as you leave the hospital, try to enter the Sebek building from the west. There will be a roadblock set up in front of the building that you can enter(similiar to a room). Upon entering the roadblock you will once again see Chris. As before, Chris will leave when he sees you.
9. Proceed with game again as usual, until you get to the cells in the police station. Upon releasing Mark and Brad from the cells, tell Brad that, No you will not take him with you. After sending Brad away, leave the police station.
10. After leaving the police station, head into the subway. In the subway you will find a room with Ellen in it. Upon talking to Ellen she will ask if you want her to go with you. Tell her, No you will not take her with you. After telling Ellen to leave, exit the subway.
11. Proceed to the factory as usual. Upon arriving at the factory you will find Alana. Alana asks if she can go with you. Tell her, No you will not take her with you. If you've done all the above steps in order, at this point Alana will tell your party that she hopes you all die, and then she leaves.
12. Now, with only 4 characters, proceed through the underground passage, beat the Sebek section of the game, and go to the alternate reality (Mary's world). When the school transforms (turns into a dungeon after finding Mary and Bruce), look for Chris in the Art room on the floor above where you start the dungeon. When you arrive in the Art room, Chris will be seen killing an ogre, then he will talk to your party. Finally, after agreeing to work together, Chris will join your party.
