Defeating Cinderblock
Cinderblock starts straight forward. Attack him until he has about half of his hit points left. An intermission sequence will start, where you will get sent into a hole in the ground. Defeat all the enemies in the new area and Cinderblock will attack you again. Then, do the team charged attack to finish him off.
Defeating Slade
This is a long fight. Slade fights you for awhile, then flees and lets his henchmen attack you. You must defeat all henchmen before he will come out of his barrier. Slade has demonic powers received from Trigon. It is better if you to keep your distance from him. When he uses his charged attack, it will cause serious damage to anyone up close, hitting them three or four times. He will attack you three or four times before you can finish him off with your team attack.
