Imagine your fire team is rounding a dimly lit, dusty and quite chilling hallway hallway, Out of the corner of your slick new helm you took from the private stash of a fallen fallen(lol), you see a darkly lit but creepy hunch that you so ever dread to know. You calmly press your emote to call out the semi hidden hive, to mark him on your map but he as already jumped and you are locked in the emote and are killed.... silly newb, you know your not geared and talented enough for the core of the moon.
