holiday_gift is a model entity available in Left 4 Dead 2, Day of Defeat: Source, and Counter-Strike: Source.

Overview

The mentioned entity was introduced in December 15, 2011 update for CS:S, DOD:S, aswell as Left 4 Dead 2, in conjunction with the achievement "Valve Gift Grab 2011 – L4D2", "Valve Gift Grab 2011 – CS:S" and "Valve Gift Grab 2011 – DoD:S" (the latter two were later renamed to just "Gift Grab").

In Left 4 Dead 2, the purpose is to collect three gifts dropped by Special Infected in Versus Mode, while in CS:S and DOD:S, collect three gifts dropped by opponents.

Features

The gifts spawn for killed special infected and tanks, not for common/uncommon infected or the witch. Only players on the survivor team are able to collect the gifts. Both survivors and Special Infected/Tank can be the killer to obtain a gift drop. Even if the Special Infected/Tank is killed by the world (e.g. Any trigger_hurt or drowning), it can still trigger a gift drop.

Factors affecting gift spawning

Several factors determine whether a gift will spawn:

1. The Convar: z_holiday_gift_drop_chance (default value: 0.3), indicating a 30% chance, with a minimum value of 0 and a maximum value of 1
2. The date: Gifts spawn between December 1st and January 2nd (inclusive).
3. Time interval: A new gift will only spawn after approximately 16 seconds have passed since the last one was dropped.

Gift lifespan

When a gift is not collected by any player, it will automatically despawn after 30 seconds.

FGD Code

Since this entity automatically disappears after 30 seconds if not picked up, it's best used in conjunction with point_template or vscript.
