Cipher Prime, the Philadelphia-based developer of the award winning, multi-platform title Auditorium [Free], is getting set to release their newest rhythm-based music game exclusively (for now) on the iPad. Called Pulse, the gameplay will have you tapping and sometimes sliding a series of dots in time with a circle that pulses from the center of the screen in rhythm with the music. It's certainly not easy to explain, so it might be best to check out this gameplay video from IndieGameMag:

Pulse is looking like an interesting new entry in the rhythm-based music game genre. I think one of the strong points will be that the gameplay seems to have been built around the included songs in the game, with a range of genres covered from electronica to heavy metal to chip-tunes. Cipher Prime has also stated that Pulse would only be possible on a device with a large multitouch screen, hence the game only currently coming to the iPad, but they haven't entirely ruled out an Android version sometime in the future either. No word yet on if an iPhone or iPod touch version could be possible.

According to the Cipher Prime blog, Pulse is already approved by Apple and will be releasing this Thursday. We'll take a closer look at the game then.

Sometimes promotions never end. At least, that's the case with Pocket Legends. In April, developer Space Time Studios kicked off an anniversary celebration that dished out free access to six areas for the generous asking price of $0. Now, the studio is announcing that those areas will remain free FOREVER � or until we all die in 2012, one or the other.

That's a deal, but you have to wonder how Space Time plans to make money while a large swathe of its instance-based content is free. That's where this comes in: the studio has just announced a brand new "premium" area called the "Sandstone Caves."

It's made for players around level 20 to 25 and includes what you want: a new town, a new series of quests, new enemies, new bosses, and new weapons, armor and items.

The price? 10 in-game Platinums, which should help satisfy the need for Space Time to fill its coffers. The lowest amount of Platinums that you can buy at the moment is 30 for $4.95, which is likely the catch here.

It's also possible to earn free in-game cash in exchange for taking part in one of those now-infamous marketing loops. "Yes, you can still get free Platinum with Tapjoy in both Apple and Android devices," a representative told us.

Just for reference, the areas that are set to remain free are Balefort Castle, Fathom Crypts, The Lost Expedition, The Ancient Swamps, Balefort Sewers, and last but not least, The Alien Oasis Trilogy.

Pocket Legends is one of the deepest, most well designed mobile MMOs on the market to date. As we've previously noted, we reviewed the game last year, but a lot has changed since then, so you'd probably be better off reading the official "Quick Start" guide to get a good sense of what Pocket Legends is about. Oh, and if you're in the market for a more in-depth look at Sandstone Caves, these two articles wouldn't be a bad start.
