Hollowpoint mod for Half-Life 2

Hollowpoint is a hitman modification that I would like to see come to fruition. Although its singleplayer I don’t plan on having a plot of anykind. Instead the player receives a contract or contracts every month that can be completed by the player. Along with the contract new weapons and upgrades to those weapons would become available. New clothes and housing spaces would become available as well to accommodate the player. I wish to have a custom character creator as well, it would allow you to tailor the kind of hitman you would want to be and that kind individuality is something a game like this needs, I feel. Along with being able to create your own hitman most if not all of the available weapons should be customizable. This game is about being given a task but after that it’s pretty much up to you to get it done with the means you have. This is basically the premise of the game that I have in my mind but I am open to suggestion. If you have any ideas or if you want to help work...
