If the game is anything like the original it's going to be pretty disappointing. On your turn you move a monster, maybe you attack something or get a power up for smashing a city. Then you move your branch of the armed forces to attack a different monster. (Combat is all dice rolling). At the end the two strongest monsters fight each other. It wasn't that exciting, if I had to explain whay I guess you could say it is missing the agonizing decisions that build tension (which could be why the game is only 5.75 in the ratings). I do think the plastic monsters are pretty snazzy.
Online demo is up at Avalon Hill's page. Looks exactly like what you're describing.
