Are you confused by the Half-Life 2: Portal video Valve showed a few days ago as part of Half-Life 2: Episode Two? While Prey uses a gun like it as well, the Portal game is based all around it and at least looks like mind-boggling fun.
“Narbacular Drop” was originally developed by a group of students at the Digipen Institute of Technology. That was before Valve noticed the project and hired them to create “Half-Life 2: Portal”. The graphics aren’t Source pretty, but the concept is the same. If you can’t decide if Portal is for you or not after seeing the movie, download “Narbacular Drop” here.
