Seven spikes. Bad. Snake's in hiding, but his new 'threat ring' - the mysterious white circle surrounding him in recent screenshots - is flashing red to indicate incoming enemies, and 'spiking' to reflect their position - the number of peaks reflecting the number of enemies. Worried? Pah. Thanks to the streamlined controls - including a contentious FPS mode - MGS4 makes combat more intuitive, less gruelling, than ever.
