Survival horror games of yore were a strange admixture of incredible suspense, and unparalleled boredom as you spent hours trying to work out puzzles that completely crippled the game's pacing. The third entry to the Resi series is a perfectly awful example of this, with its notorious water sample puzzle. Faced with a control panel that means absolutely at nothing at first glance, you must stack little coloured blocks in three rows and eight columns on the panel so that they mirror those shown in the sample section at the top of the panel - deeming the water safe. You cant just move an individual block on the screen either, and are forced to slide a whole row, which throws all the seven other rows out of whack. Spare a thought for the water quality inspectors of Raccoon City who have to go through this tedium every day of their working lives.
