SWAT 4 looks great,but i don't think it will be so how do you say in English uhm,commecial and popular enough to sell enough copy's of SWAT 4, i think it's a great game, but commercial for fps nah
SWAT 4 has some great aspecs. For one it shows you somewhat of an insight of what SWAT actually does. Though it lacks in a more candid type of suspect. When you come across OPFOR hearing "Holy shit the cops" every single time does tend to become boring. And the fact that suspects don't really warn each other and do their own thing instead. There has been times in rooms when suspects would be side by side and one would surrender while the other face the furry of 9mm shells from my H&K MP5.
Overall its a great game, alot of neat levels showing all aspects of what SWAT does. And best of all it shows you some of the crazy junk they have to put up with while out on OPS. If you haven't played it yet you should, immediately.
