Then there's the also-publicised Deadmau5 inclusion. He gets his own megamix, though I wasn't allowed to play past a few tracks because other people wanted a go. Jerks. Still, breezing through I Remember was ace.
Even more interesting, at least to me, was D.A.N.C.E. by Justice (getting on a bit now, but still great), an in-house remix of MSTRKRFT's Bounce and a mash-up of Edwin Starr - War with Stevie Wonder - Superstition. Oh, and House of Pain. House of Pain! The oldies (as in, pre-millennium) were the least popular tracks in the original (FreeStyleGames has technology which can tell what's being played) but there's still plenty to be had; the studio loves them too much to not work on them.
Certain tracks will pop up in various guises, though the repetition seems to be less obnoxious than in the original – far fewer instances of Gwen Stefani's Hollaback Girl, basically. Held directional scratches have been added to spice up the mix, and the new freestyle sections – allowing far greater control over the sound of the mix – work to make the player feel more connected to the music. It's a little touch, but it goes a long way.
Then there's multiplayer. Poorly implemented and overlooked in the original, a new suite of modes have been created to encourage party play. Cut and paste battles are the primary inclusion, allowing back-and-forth (think Run DMC) sections with custom mixes made exclusively for the mode. It's a lot of fun, tougher than the standard competitive Guitar Hero and Rock Band modes because you're aware all eyes are on you as you struggle to keep up on your sections.
Another mode is accumulator, which functions as a DJ version of The Weakest Link: you have to 'bank' your streak else lose it when you miss a note. It's a fairly hardcore mode as it requires a lot of skill, not to mention the inevitable frustration from missing a key means it won't work too well in a party environment (when you've had a few beers). Checkpoint is slightly more relaxed, and has you duelling to rack up the most score across sections of each track.
Again, these modes are incremental additions rather than revolutionary new features. DJ Hero 2 isn't trying to reinvent the turntable, but by keeping the range of options consistent and adding in an impressively bulging tracklist, FreeStyleGames is creating a very promising sequel. Make no mistake, this could quite easily be the defining moment for the series.
DJ Hero 2 is due for release on Xbox 360, PS3 and Wii on October 22.
