This game has multiply stages.
The goel is to dispose terrorist invading an embassy. And save the hostages if you can. I think you only got game over if you lostyour team, the time ran out, or ALL the hostages died (by your hand).
First you picked each member, and tried to reach the marked hiding spots, while avoiding the reflectors of terrorist snipers. This part is very very cool, you realy could do stunts with the limited resources.
Second you could adjust the starting position of your team on an upside-downminimap. This marked where your snipers start.
Thenyou used your snipers to pick down terrorists through the windows of the three sides of the embassy.
Then you lowered one of your strike team to infiltrate the building. If you entered a room with an evil person, you died. If you lost all three soldier, you lost.
Then came the indoor clearing of rooms,which was a bit clunky, and dangerous, so you better picked as many from outsiude by the snipers as you could.
And that's it.
