Luk's Perspective is in the top right corner. You can hear him talking every once and a while. He doesn't have a mic yet so his voice is competiting with the sound of bullets, grenade launchers, foot steps, air support etc.
Good lesson for all those noob spawn trappers. You shouldn't be dying like a noob while spawn trapping. You should be building your kill streaks up when the other team only has one flag.
