At one point in time I wanted to make a Half-Life mod. In the style of the the gearbox expansions. Instead of playing asother scientists, the army or a security guard the player got to play as the G-Man. It was going to take place during the resinance cascade. You were going to start by delivering the sample to Dr. Breen before travelling to the army base where you see shephard doing the army training. You could collect a gun pistol. The main idea was you were going to see actually take part in every G-Man sighting from all Half-Life 1 and all 3 gearbox expansions. As your goal you would go from area of Black Mesa to another area collecting Xen samples and observing Shephard and Gordon. With the game ending after Gordan is placed in stasis. You would fight Xen creatures and race-x. As each Xen crystal was gathered it would unlock a new "ability" (weapon). These would be things like chain lightning, displacement blasts, vortigaunt blasts but also featured utility like a self heal.
Status: Abandoned.
Amount of progress: Fully designed, never built.
Reason: Too hard and too much time.
