This project attempts to integrate the whole Half-Life experience into a single playable modification. Experience the boundless possibilities of the Mark IV Hazardous Environment Suit as it begins to accept weapons from beyond the reaches of the old Black Mesa. Your arsenal has been dramatically bolstered, allowing you to become more powerful than ever. However, as your firepower expands, so does that of your enemies. Therefore, it becomes even more important to adapt to your environment—to use what is available to you in order to survive the onslaught of your hated nemeses.
