The game is basically the same thing from 1986, but with fancier graphics.
Graphicswise, they breathe new life to the series. While the artstyle of the graphics are more cartoony than serious, they shine all the way, with 30 monsters to unlock and to choose from. An interesting aspect is the backgrounds and faux-pa billboards trying to spoof popular media, such as Seigried and Roy, The Hard Rock Cafe and the musical "Rent", among others.
As far as sound is concerned, they're good, but a little bit monotonous. Depending on which city you're currently destroying, the various citizens of the cities will repeat the same voice-acting lines over and over again. One of complete concern is the traffic reporter, using really bad puns during the death and destruction of a monster attack. Also, the soundtrack of the game is more rock 'n roll than epic music.
Regarding controls, it's Rampage at it's best and then some. Aside from the usual buttons for jumping, punching and kicking, there are advanced controls where you can ram your feet into the building, causing the entire current floor to shatter, a roar attack and a few other controls that require upgrades to learn them.
Gameplaywise, it is good, but the tried and true formula is completely weakened. All you're doing throughout the entire game is smashing and destroying buildings, while eating various items to either recover lost health or lose even more of it. A new, but minor, inclusion is the challenge system, in which you have to do certain tasks, such as eating 20 soldiers or destroying 5 buses, for example, in order to earn bonus points. Unfortunately, you're also suppose to complete the challenges to earn your special attacks, which makes it a "do-it-or-suffer-the-consequences" proposition in the long run. Also, the game has emulated versions of the two arcade Rampage titles, from the get go. If you're going to complete a game of mindless destruction, at least make the arcade games as unlockables as an incentive.
Overall, it is a fun little game, although the formula of the series might not hold out much longer than it already has.
