Troubled Tower

You are Jack 'Calculator' Hayes, a mild mannered attorney until one day... Shane Conway Computer Designs, a large company, is also a front for a C.I.A. base held underneath the building. A secret militia group, led by the mysterious Master Dinkins, takes the building by storm. As you are walking down the street to get a cappuccino from the local coffee shop, you hear gunfire from inside the building. Remembering all those self-defense classes you took in the third grade, you enter the building.
