Shield

The Shield is an item in Check It Containment Facility, and is mainly used to protect oneself from incoming damage or a CiC's attacks.

In-game
In game, the shield is only a default item for Emergency Task Force, Default Occult Coalition, and the Biohazard Cleanup Crew (as the Bio-shield). It is also given to those who have purchased the Hostile Test Subject Bundle which grants (besides an AK-47 and Level 3 Keycard) a shield.

The shield is primarily defensive, and when in use, will give a force-field around a player for 8 seconds, and any damage directed towards the player who has the shield active will be negated, such as shots from any gun and attacks from CiC's.

Bio-shield
In the game, Biohazard Cleanup Crew players will receive a variant of the shield, known as the Bio-Shield. While the shield functions identically to the regular shield, what makes it different is its different color scheme and that it's probably meant to be used to protect against biohazards.

Appearance
In-game, the shield appears as a semi-transparent white shield with a black rectangle in the middle, along with black shield handles (essentially a riot shield).
