News & Rumors Half-Life

A user from the Steam forums appears to have found several AI node entities from the Alien Swarm SDK. There are several entities with the abbreviation ‘Ep3’ included before their actual function.

The AI entities could refer to some sort of blob or dynamic matter. According to our newest staff member Pinky, this blob can perform several actions such as drain itself possibly into a drains or sinks. There has also been found to be another AI entity called ‘Aperture: Nest’ however it is currently uncertain what this could be.

In the meantime it appears that there is a large discussion on the Steam forums so maybe we can expect some more information sooner or later.

I would like to thank Pinky from Capture The Hill for discovering this story.

  3. Valve is working guys, they must be in the test stage before the art-pass or some where in between.

  4. Ep3 is a lie

  5. Valve is trolling us again. They had to drop some EP3 news, and this is a pretty wacky way of doing it.
