I've been trying to remember this live action TV show for years now.
In it teenagers wherewere able to enter this virtual world of sorts and they become these avatars. Their goal was to clear levels and move on to the next and I don't remember why. There were artifacts or items that help them on there whytheir way and they can return to the real world easyeasily enough. I think and they can re-enter the virtual world through someone's school I think.to pin point
To pinpoint a possible date im thinkI'm thinking maybe 2000s to 2004s, it is hard to remember because iI was so young.
