OOC: Combined attacks in M&M only add to the chance to hit a target. As the mostly glass door is an immobile object, simply concentrating when attacking in hand to hand is an automatic hit. Combined attacks don't actually do more damage.
IC:
Spyder, Diva and Infernal try to time their attack on the ice-covered glass door. They are mostly successful and the glass breaks into little bits of glass mixed with ice. With the glass knocked out, the sounds of the raging storm inside are easily heard.
Beyond the entrance is a smallish lobby. To the right is a short staircase leading down into the main casino floor which is completely engulfed in the raging storm. To the left is the hotel check-in desk. No one is seen in the area.
Ghost reaches the center of the main casino floor. Below him are blackjack, craps and roulette tables. Evidently, the cause of the storm isn't located in the center of the room. In fact, the storm isn't actually centered in the room. It engulfs the entire room. While flying, he passes over a few individuals who are trying to take cover under overturned tables and other furniture. These people appear to be patrons caught in the place when the trouble started.
Eve also locates a few patrons attempting to hide from the chaos under overturned furniture. All are scared and very wet.
