Crack is a highly addictive illegal substance that will make you do stupid things in order to get a steady intake of it's fix, often sold in vials. The term crack can also be applied with similar definition to non-illegal substances. The Capcom's Versus series is crack. Therefore it's only fitting that
Marvel vs. Capcom 3's story trailer has the universe's combatants fighting over a vial of the good stuff.
