Entities Missing

[Barfdude]

Ok, so, I was lookin through the example maps, the citadel ones in particular. I noticed a lot of entities I don't have, and some I want, like env_citadel_energy_core. Does anyone know how to get those entities?

Edit: Nevermind, I'm retarded. Just had to add a fgd file
