The brief demo that we saw showcased a battle between the two premiere forces of the Halo universe: the humans and the Covenant.

Keefe brought along lead guitarist Paul DiGiovanni, with whom he had recorded a brief demo, to complete the line-up.

Anyway I asked him about the 'Touchscreen PC' he was playing with and after a brief 5 minute demo I am amazed that this OS has been released.

Using friends, they produced a brief demo and began shopping it to multimedia publishers.

I took a peek around the discs and found there were a lot more files than there needed to be for such a brief demo (one level set in Las Vegas).

There are 25 audio tracks in total on the CD, the hidden tracks were brief demos and were never used in-game.

BioWare also presented a brief demo of Wrath of Heroes at Gamescom.

While my brief demo didn't tire my arms, I could definitely see wanting to rest the unit on a table or my lap if I were playing for a long period of time.

Ars recently played a brief demo of the game, and unsurprisingly, there's not much we haven't seen before.
