Now this is fun. I added another parameter to the basic tile model and that is explosion strength. If set, the tile has the capability to explode (like computer terminals, video screens, gas tanks… etc). Shooting or throwing grenades at those tiles can lead to chained explosions (more tiles explode at the same time). The feature is implemented, and there is no better way to test it then to plant an explosive in the middle room of the map, where the computer terminals are (marked with an ‘@’).
