There is nothing truly original about Mercury Meltdown, it is really just another Marble Madness / Monkey Ball style game, where you have to tilt a world in order to get a physics based object to a goal in the level. But there are some subtle touches that make this game very enjoyable and frustratingly addictive. This game is a sequel to an older PSP game Mercury, with some of the problems from that game addressed here.

The first thing to note are the wonderful graphics. This game looks fantastic with its bright and colourful graphics that really draw you in. The lighting on the blobs of mercury look great and the impressive fluid dynamics on the mercury looks fabulous. Mercury can be merged with other bits and a cool colour changing system allows you to tag your Mercury and allow it access to certain parts of the level.

The second to note is that this time around, the challenge seems a lot more forgiving. There are still some insanely frustrating levels, but on the whole, this makes great gaming on the go. I've had a lot of fun with this game and prefer it to the Wii versions for its portability and because a game that requires the level of precision that this game requires, works better with a analogue stick compared to holding a wiimote.

Overall, great fun, and recommended for anyone after a bit of a challenge.
