An Icy Battlefield

It starts with an unforgettable roaring sound, Like nothing I'd heard before. There's people and protection all around, while my feet slide on the cold hard floor. Armed with only one simple twig, And two knives strapped to my feet. I move forward like a ravenous rig, Never slowing or missing a beat. The wind plays music through my ears, My heartbeat begins to race. Losing mind of all my fears, As my enemy becomes face to face. There's only once chance for this to work, So I focus in and take a shot. As I can hear the enemy allies lurk, I know I've given it all I got. Suddenly the sound of a siren, As I hear and become cocky. There's no sound of hit iron, Which is the best when scoring in hockey.
