Entity Description

Creates a red flare. Useful for creating a dark environment with just enough light to navigate. The flickering red light of the flare creates a tense atmosphere and a strong feeling of fight-or-die, as it's mainly used in HL2 only by the Combine.

Note: This entity is derived from CBaseCombatCharacter and can have relationships defined towards it.

See the beginning of d2_prison_08 for an example of its use.
