No Levels 13 to 19 in Portal First Slice
I have an issue with Portal First Slice. Maybe I've missed a s/w announcement somewhere along the line; but, Portal First Slice doesn't go beyond level 12 any more! The elevator ride from level 12 stops at the entrance to level 13, but the entrance seems blocked (just a black, opaque panel). Also, the lighting in the elevator dims just as the elevator stops at level 13. Is this the way with First Slice now - no more game beyond level 12? Or what?
