New game / mod in the works: Half Life Medieval Siege Simulator

I am making a mod for HL1 in which the player can partake in a historically accurate siege. The player's interactions will be basic at first, and there will be no enemies to fight but as time goes on I will add more content like the aforementioned. When I have finished the first build I will make it available for download (for free as always) with instructions on how to install it included, as obviously I cannot just freely distribute a slightly edited copy of Half Life. Stay tuned for updates and the completion of the mod! UPDATE: First part ready in new post.
