Interactive items (you can turn on/off showers, eat food items or drink water from any faucets to recover health). Destroyable cars, trees, driveable tanks.

You will notice thousands of new additions: The first beta was formerly released under the name 'Hell on Earth Starter Pack'. Extermination Day is Brutal Doom's canon campaign.
