This mod makes the player invulnerable. If the player is inside a vehicle, that vehicle will also be invulnerable, until they leave again.

Biters will not attack the player, but they will attack and damage the factory and any unoccupied vehicles.

The invulnerability can be enabled/disabled in-game. In multiplayer, this setting applies to all players and can only be changed by the server admin.

Note that shields can still take damage.
