So what are you waiting for? Get Steam and download it! For PC and Macintosh.
This is a time limited special offer, since now Steam sell Mac games too, you can get your Portal game for free until May 24th, so hurry up..
Prometheus is a mission-based, single-player co-op game in the spirit of “Portal” and “Mirror’s Edge.” By using the Prometheus Device, players bend the laws of Einsteinian physics using the theory of quantum states, meaning that goals are accomplished by completing missions with your past, present and future selves.
This standalone version of “Prometheus” was created using UDK. You’ll need to keep your wits about you and your memory sharp in solving puzzles presented with this unique game play mechanic. Progression through the story introduces new challenges, with tasks increasing in difficulty, and a final dramatic conclusion questions present loyalties and even your own existence..

Authors:”Gaming technology on the web is changing. InstantAction is bringing 3-D multi-player console-like games to the web, playable through a browser. The platform brings together the best of gaming with the best of the web, combining the web’s accessibility and social interaction with high end graphics and competitive gameplay. This will appeal to hardcore gamers who find the games more accessible than expensive console games, international gamers who don’t have access to consoles, and former core gamers who have careers or families and no longer have as much time to pour into the gigantic game experiences they used to. We have cracked some daunting technology hurdles to bring the type of games serious gamers like to the web.
Since many of our games are online and multi-player, we have designed a social environment that makes it easy for friends to connect and jump into a game. In addition, with InstantAction’s unique lobby approach, it is easy to move from game to game with your party. Being on the Web also enables us to do what we call “live development,” where we take active and passive feedback from our players to continually update/improve levels, storylines and gamers will no longer have to wait for a sequel to keep a game fresh.”
This mappack includes ALL 40 levels from WCS’s Flash version, additional bonus levels and features. All together, we’ve got here over three and a half hours of amazing gameplay.
Requires Steam with Half-Life 2 and Portal installed in order to play
I think everyone knows Kongregate, the famous flash portal, i took the best of december 2007, i found some of this games to be really good, Mardek is a old-school rpg in flash, then we have Monster Den which is a dungeon master in flash, reminded me lot those old boardgames and finally the (ultrafamous) 2d version of Portal, the famous game included in the Orange Box.
p.s talking about portal you can give a check at Narbacular Drop too.
So if you have 5-10 minutes to waste, give this flashgames a go they are pretty entertaining…
