Now, I understand this game is a game based around Emergency services but having other services will just extend the game's outreach and will help current calls be even more realistic. Mission Chief has the potential to expand the content instead of sticking with the emergency services. The services that will be listed below would change how people will approach the game and may even extend the player base.
Network Rail - Network Rail is the main railway response and maintenance company in the whole of the UK. With the implementation of Network Rail or something similar, it can extend the current railway calls which could require Network Rail to do maintenance and clean up. Also with separate network rail calls such as Points Failure, Track Obstruction, etc. Then along with this, we could have a railway expansion to facilitate things like BTP and the Response Unit which they have. Also maybe could be more than network rail and transport response units which lots of companies do have.
Vehicles:
- Response Vehicle
- Maintenance Vehicle
- Command Unit
- Road Rail Vehicle (Could be added for fire services also as some have these)
- Maintenance Train
Highways Agency - I think most people know what the highways agency is but for the same reasons as the ones above but you could have motorway calls expanded for cleanup and maintenance. The calls for this could be, Person on the Motorway, Broken down Vehicle, Broken motorway gantry. This also could facilitate recovery companies being an extension which I will get on to.
Vehicles:
- Traffic Officer Vehicle
- Maintenance Vehicle
- Incident Response Vehicle
- Gritter
Recovery Companies - Very simple and self-explanatory but extends calls and can create more calls for the player base.
- Roadside Recovery Vehicle
- Flatbed
- Flatbed + Boom
- Wrecker - (For Heavy recovery calls)
I imagine more people could add on for calls, vehicles ect so will leave the rest open.
