This is a great game, albeit with a few significant problems.
The Gameplay is the best part of it, where you have to simultaneously deploy and manage multiple response units including firemen/firetrucks, Ambulances/Paramedics, Police, Negotiators, Salvage vehicles etc.
You start in a suburban area where you respond to numerous events. The game quickly manages to scale up and has you managing multiple units at the same time, in different areas of the city, all earning you money to purchase new equipment. When you have the required equipment it unlocks a "mission" that takes you into a separate "mission map" and you get a more complex mission. When you complete the mission it takes you back to the suburban area again, to manage more random events until you have purchased the required hardware for the next mission.
This gameplay is quite fun, and even though it is the same incidents, the map is quite large and always has you thinking on "where is the nearest hydrant?", "what resources do i need for that?" or "where is that criminal running?" so each incident is still quite unique.
Now, the "significant problems" I mentioned earlier (from least significant to most significant)
Firstly: Audio is ok. It repeats a lot of things a lot of times and has some interesting things (like every vehicle you click on sounds the "ambulance sirens", even if you click on a car on the side of the road)
Secondly: Graphics are ok. It doesn't have any options above 1024x1280 and on a full HD display it is somewhat grainy, but I don't think this significantly detracts from the game
Thirdly: When doing the more complex "Mission scenario" I still haven't found a way to restart it without quitting to windows. So when you make a big stuff-up and all your firemen are dying with a wall of fire between them and the paramedics, you actually have to deal with the situation... or you quit to desktop and start the game again
Next: Each individual will not really do anything unless you have told them to. ie: A fireman will watch a fire burn, unless you have told him to equip an extinguishing device (hose or extinguisher) and is within range. If a fire moves out of range, he won't follow it. Same goes for Paramedics and Police. I'd love to see a little bit of automation, such as: tell the fire-truck to "CONTAIN" the fire and they setup automatically to stop the fire spreading, or tell the paramedics to "TREAT" the casualty, and when he is ready for transport they should automatically load him into the ambulance and take him away.
Oh, and firement shouldn't stand in one fire when trying to fight another fire... yeah this can happen.
Lastly: Traffic routing. If you order ten ambulances (yes, i made a few mistakes fighting a fire once) and tell them where to go, after the first two arrive, then the others keep driving around in circles because they can't get to the spot where the first two ambulances parked. Sometimes they'll drive around a building on fire and blow up because they are trying to get to that exact spot.
And sometimes they get "jammed" because they drove too close to a pedestrian and then you have to manually "unjam" them so they can drive again. (not too common)
But, all in all, a good, enjoyable game, just be warned that some things are frustrating
