SWAT's convoluted story line takes place in a poorly-represented New York City. At first, players must engage warring Korean gangs that have civilians in the crossfire. Inexplicably, the fights will have you gunning through subway stations and office buildings in a search for a ... dirty bomb constructed by Islamic fundamentalists? The story is haphazardly constructed and does little more than magically transplant your team from one locale to the next.
The main star of the game is Wolfe, and at his disposal are three squad mates (two of which can be used in each mission). Theoretically, you can change weapons and characters, but there's almost no compelling reason to do so. Each mission can be tackled with the same gear and the same characters, thereby greatly reducing the amount of "tactics" the game should have.
