A conflict of star-spanning proportions - with Earth caught in the crossfire! For those eternal intergalactic enemies, the merciless Kree and the shape-changing Skrulls, have gone to war, and our planet is situated on the front lines! Can Earth's Mightiest Heroes, the Avengers, bring about an end to the fighting before humanity becomes a casualty of war?
