I'm stuck in the lab with the Key, where you have to free the scientists using Flash and Green Lanter. What can I do?

There are crates nearby, smash the crates and inside there are explosives. Throw them at the door. Or activate FLashes super speed and wail on the door. But that doesn't work unless you're really up on your stuff. Use the bombs.

Me and a buddy played the #### out of this game when it first came out. We finally figured you have to free the scientists first. That takes off the time limit. There's a computer console at the back wall for each room the scientists are in. Do that first.

Once done what we did was I flew around (I was GL) and just kept firing bolts at the Key, while my buddy kept using his tornado power to keep the enemies off me.
