Fulfilling GameSpot's commitment to both highbrow culture and toilet humour, this week's tests contain:
a. Lovely opera
b. A toilet
But a giant one, mind you, full of turrets, that you can flush with the power of portals. This latest batch of player-made puzzles have Cameron and Jane navigate that colossal lavatory, sneak into a sentry turret opera, and play a spot of golf with Excursion Funnels.
