Kotaku has a preview of Impulse Phase IV.
Impulse is a new digital distribution platform in which PC users can purchase, download, install, and update any type of PC program games, utilities, applications, etc. Launched about a year ago, Impulse has increased its user base at an exponential rate as it has gotten the support of major PC software and game publishers such as THQ, Ubisoft, 2K Games, Activision, Corel, Paradox, and many others.
The new version of Impulse comes with an update client that allows users to associate their purchases with a single account. When a user who gets a new PC can then install Impulse, logon, and then download and install all their Impulse purchases easily. It also includes a new store designed to handle the vastly increased library of games, applications, and utilities that have been being added over the past few months and to prepare for this Fall when back catalogs from major publishers are being added.
Stardock will be demoing the new version of Impulse at PAX with it becoming generally available in September.
