'Still, it is fair to say that sneaking around is just the tip of Metal Gear Solid 4's Titanic-sized iceberg of action entertainment. Brace yourself for a lot of variety as the narrative twists and turns to catapult you across the globe in a flurry of game **** and approaches to design. You'll find yourself climbing on car roofs to eliminate shambling hordes, or donning a raincoat to evade security forces while tailing a mark. One section requires you to use all of your wilderness skills to track down a target, scrutinising the way ahead for signs of your quarry. And, of course, you'll find yourself encountering fiendishly devised bosses. Because where would Metal Gear Solid be without bosses? As if to remind you, several of the bosses in MGS 4 are brilliantly evocative of some of the more memorable boss encounters from the series so far. They also prove to be pretty memorable encounters in themselves, too; running for cover through a research lab, while trying to locate a stealthily camouflaged femme fatale, for example.'
