I'm at the point where I must enter the secret laboratory. I know exactly where it is, but can't get there - blocked by force field. Thus the game is over as this is part of the main quest. The game didn't cost very much and I can see why. I'll move on to something else. Be warned this game is very linear and if you do something in the wrong order you may findd your progress blocked. I don't recommend buying Van Helsing.
