Three minutes of what seems like the whole world blowing up around you on Modern Warfare 2's 'Favela' multiplayer map, and you're exhausted or you're dead or you're both, in that order (and that's if you're just watching). Glaring virtual sunlight shines on a ruined, gloriously-detailed, sprawling slum as far as the eye can see in every direction. Three out of four walls have big holes blown into them. Constant threats to your team (and theirs) are common lines of conversation. There's nowhere to rest safely for more than a few seconds. A constant cacophony of panicked radio-chatter and gunfire thuds through the air. Violent spatters of blood gunk up the screen.
