3dGamers has the E3 movie of Human Head and 3D Realms's first person shooter, Prey. This almost 180mb DivX movie shows 11 minutes of gameplay footage.

Those of us that remeber the original Prey announcements many years ago will be pleased to see a lot of use of portals which lead from one map or area to another, sort of like Alice through the looking glass, I guess you'll have to watch to get my meaning, but these portals were the source of much discussion back in the day. It would seem that gravity manipluation and physics also play a big part in the game.

This is well worth a look, even if it's just because it's different.
