So, I made a custom SWAT 4 level based on Dirty Harry: Sudden Impact..., help me learn about SWAT 4 mapping Options

So, one nice thing about SWAT 4 and the Stetchkov Syndicate expansion is that they allow the user to make his or her own custom levels. I've been experimenting a bit with this lately and with a fair amount of ease I made a little scenario based on a scene in the beginning of the Sudden Impact Dirty Harry movie.

The scene is a pretty cute one. Dirty Harry stops by a diner on the way to the police office in the morning to get his daily cup of black coffee to go. Before he arrived, a gang had actually stormed the diner in order to rob it, and they threatened everyone into keeping quiet while Dirty Harry is getting his coffee. Dirty Harry's reading the newspaper and not paying attention to his surroundings so he doesn't notice and leaves with his coffee, but the coffee shop worker put a huge amount of sugar in Dirty Harry's coffee, which caused him to come back to complain and see the robbers back at shaking everyone down. So he walks in the back door at that point and blows all the bad guys away with his .44 magnum revolver, and then we have a little bit of fun where he quizzes the last ganger into surrendering on the subject of whether or not there's a round in his chamber.

The built-in customization is easy to do, but also very limited. Basically it lets you use the maps already in the game and adjust the parameters, such as number of NPCs, their morale level and equipment, the mission objectives, a time limit, and so forth. It basically lets you do everything that is easy to automate. However, it does NOT let you place the NPCs, add or remove things from the level, specify player equipment, and so on.

So for my experimental learning experience, I used the Food Wall Restaurant map, put in 10-15 civilians, and 7-17 gang members with random pistols, and set the objectives to Bring Order To Chaos and ensuring that no harm is done to the civilians. I removed Rescue All Civilians so that it's possible to run through the level and shoot the bad guys like Dirty Harry but not take the time to go and cuff all the civilians as well, which wouldn't be in keeping with the scene from the movie. Since there's no way to set player equipment I just added a description along the lines of, "For the full Dirty Harry experience use only the magnum revolver" instead of flashbangs, CS gas, tasers, and so forth.

Now, it seems like a very fun, and safely modest mapping project could be making a small diner like the one in Sudden Impact, have the player spawn at the back door, and have the player spawn with only the Colt Python and no armor. The level would just be a quick shootout with a few enemies with a Low skill setting and the challenge would be making sure that none of the civilians are caught in the crossfire.

Does anyone know if it would be possible to map/mod up such a specific scenario for SWAT 4? If so, what software would I need?
