Demonstration:

The package includes:

1. Plugin
2. Gift model (screenshot) (Workshop upload required)
3. Two sounds: for drop and pickup (see video) (Workshop upload required)

Currently, when picking up a gift, only the command specified in the config is executed. A transition to a modular system is planned for the future.

The gift model was taken from here and ported to CS2.

The plugin is provided without binding and without source code.
