A deep and entertaining experience that can mostly, if not only, be savored by those without itchy trigger-fingers.
You have a vast arsenal of armaments at your disposal, which come in different classes. You have a primary weapon slot and a secondary weapon slot, including a tactical slot that contains useful tools such as gas grenades, flashbangs, door wedges (used to prevent a criminal from breaching a certain door), and other such useful stuff. The most interesting tool of all is the Optiwand. A miniature camera attached to an extended telescope, which you can use to peek around corners and under doors. All these tactical tools help you win each mission
The most interesting twist to the gameplay element is that it is not all run-and-gun, you must first try and arrest the criminals and if necessary shoot them (but not kill them). Because of this the game moves at a rather slow pace (which is the most necessary element in a tactical shooter), but it does that in such an addictive way that you're stoked to play more. There are a total of 14 single player levels and even though the number is pretty weak, the difficulty and re-playability outweigh that one flaw. Tactical shooters rarely fair as well as SWAT 4.
One of the most important element in a tactical shooter is the AI and SWAT 4 delivers it in spades. Brilliant is the only word that can describe it. Turn your back on a stopped criminal for a split second and he'll blow your head off. Hostages can sometimes get a little stubborn but a gas grenade or a good whiff of a little pepper from your spray will set them straight. A brilliant interface backed by a cohesive AI makes SWAT 4 easy to recommend to fans of tactical shooters.
