So, all you do is fell enormous beasts, one after the other. Not the most complicated of set-ups, yet Shadow of the Colossus is one of the most beautiful, heartbreaking and imaginative experiences on PS2.
Here's PSM3's pick of the most epic moments from Team Ico's spectacular giant slayer.
1. When the first colossus appears
Even if you'd seen screenshots before playing Shadow, seeing a colossus in motion for the first time is a humbling moment. This guy's not particularly threatening - he just lumbers around as eagles circle his head - but the moment you get his attention and the music pipes up, you suddenly feel small and powerless. Of course, all it takes is one stab to the back of the shin and a few in the head to end his days. It's a brave game that introduces you to such a bewilderingly huge enemy in the first ten minutes of play.
2. Taking flight
Fire an arrow at the birdlike fifth colossus to attract its attention and grab its wing as it swoops down to attack. The beast squawks in panic and yanks you violently into the air as the soundtrack swells to a dramatic crescendo. It's an unforgettable moment, and one of the most terrifying and exciting 'levels' ever designed. To get to the beast's weak spot you have to cross an area with nothing to grip, meaning a death-defying sprint as it briefly straightens its wings. Don't time it wrong, now...
3. Scared of fire
At first this tiny colossus seems unimposing, but all it takes is one hit-and-run to knock you over and lop a huge chunk of his health off. To defeat him you have to get creative. If he bumps his head into one of the flaming pillars in the arena, a stick will be revealed. Then it's simply a case of setting it alight and waving the flames at the colossus. He'll edge backwards until he ends up toppling off the edge of a cliff, shattering his armour and revealing his weak spot. Ingenious.
4. Exploring the Forbidden Land
Shadow's world is just so darn nice to look at, and rich with character. The ruins of whichever civillisation once inhabited the Forbidden Land litter the plains; most impressive of which are the temple and its connecting bridge. The fragmented buildings suggest some epic cataclysm that cleared the land of its former inhabitants, which makes the world seem even more ghostly and eerie.
5. The Guilt
Rather than the clumsy good/evil divide most games draw between player and 'enemies', Shadow lets the gamer decide if what he's doing is right. Is the life of one girl worth that of 16 creatures? When you see their gentle eyes as you stab at their heads you realise you might be the evil one.
6. The turtle colossus
This turtle, with massive pillars for legs, constantly fires pulses of health-sapping energy at you and stomps on the ground to shake you off your horse. But thanks to some handy geysers, you can flip him on his shell and leave him defenseless. Lure him over the water and the power of the jets will flip him over. Then you can clamber up his soft belly and get on with finding his weak spots.
7. The sword colossus
You have a sword and so does the third colossus - but his is the size of a petrol tanker and is made of solid granite. But there's a metal pad on the ground, and standing on it attracts a swing of the big guy's weapon, resulting in it smashing and forming a point. Perform the same technique on the soft soil and it'll get stuck, letting you run up the 'blade', crawl up his arm and then get busy with the head stabbing.
