Ent_create
Please note that the video memory for ent_created entities is only allocated when the entity is seen the first time. This is one of the tricks used in Serious Sam that has allowed them to have hundreds of enemies in a single level. The entities are created when the player comes close to a certain area.
Decal
This flag makes a sprite one-sided for attaching it to a wall; Half Life makes heavy use of decals.
