They released an expansion I think as well, I only have the original version..
-It was a lot of fun online, doing the coop missions, although your score normally tanked due to your team mates dying -or you dying, since the higher difficulties gave the computer insta head shots-
but the worst parts of the game are handcuffing everyone, and picking up weapons (which seems like BS to have to pickup suspect guns -wheres the CSI halt THATS EVIDENCE! patrol when you need it?)
--Having to pickup all the weapons also ends up being the thing that makes matches take so long -Its always one missing gun, and no one can find the darn thing-.
==================
For the most part the Idea is you start off in a location based on your selection for entry into that map -then you check room to room using all your little gadgets per swat member
=checking under doors with a camera scope
=bashing open doors or slighty opening the door to see whats inside
--as well you can give commands to your npc buddies in the single player to open and throw in flash bombs or sting balls, then you rush in hoping the enemies either ran or are dazed enough that you can YELL at them to drop thier weapons and then handcuff them.. then rinse and repeat till maps finished...
-Theres also a sniper option in some maps, you see from the snipers POV and control his aim to take out a suspect =one of the maps is like a gas station or little food mart and its being robbed,=
But it has its suprises, the AI isnt completely stupid, but its a bit random in thinking it needs to open fire on you in most cases.
