Freeverse continued it’s “Big Week” series of announcements today with the introduction of Big Bang Brain Games, a suite of six games designed to stimulate the cerebellum, cajole the cortex, and gratify the grey-matter, notes the company. Big Bang Brain Games offers tight integration with Apple’s .Mac service. As the player succeeds in the various challenges, his or her overall Brain Score will increase and the game provides a simple means of creating your own Brain Page via a .Mac account. Freeverse is also making Big Bang Reaction available for download today. The game is fully unlocked but the download link will only be up for 48 hours.
