Visually, it's impressive, but not staggering. Squint and pop into first-person view, and it's not dissimilar to the Middle East sections in Call Of Duty 4. In fact, playing MGS4 in FPS mode feels initially disappointing, since a part of your brain thinks you're playing Infinity Ward's incredible shooter. Extended play soon erodes comparisons - Metal Gear 4 is way more flexible - and the graphics gently dazzle: the volume of gunfire, explosions, soldiers and smoke in the final showdown with the PMC tank spikes your breath.
It isn't PS3's best-looking game, but the solidity and detail - zoom in and just look at Snake's grizzled face - is confidently reassuring.
