Hint: Raining enemies:
In Savage Time, make sure you have a superhero that flies (not Flash or Batman). After the Superman Zeppelin bonus level, make your way through the interior castle, to the second bridge (the wooden platforms with soldiers walking). Make sure your hero is on the bridge, then press Up(3) time to fly. Fly up the screen and keep pressing Up to hear punching sound effects. Soldiers will fall down your screen; because your hero is hitting enemies off your screen view. Note: Your hero will only stay in the air for five to six seconds before landing. Note: You must have a flying Justice League hero, in order for this trick to work.
