The open beta commenced on December 9, according to the Web site for the game.
"Neosaurs is a new massively multiplayer RPG (MMORPG) adventure that you can play, right here in your browser for free! No downloads, no wait times. Click 'Play Now' to jump in the game and start playing right away with your existing Facebook or Windows Live account," according to the Web page.
I asked Microsoft about Neosaurs and received the following statement from a spokesperson:
"Neosaurs is a new game under development at Microsoft Game Studios in partnership with Camelot Media Investments (CMI), a global leader in the casual MMO space. The game is actively under development and currently in beta. We will have more to announce soon."
"Al Ahli Gaming has invested directly with the launching of Camelot Media Investments and will have first look opportunities to the line-up of coming games about to be released. Industry experts have classified these new games as 'the new face of gaming,' according to Al Ahli's site.
Neosaurs is interesting on a couple of fronts. For one, it is evidence of Microsoft's growing interest in the casual gaming/social gaming space.
