You are the leader of a SWAT (Special Weapons and Tactics) team, that means, you are the man in charge of making sure that the hostages, the casino's money or the President of the USA get out of each situation unharmed. You have to make sure you or any of the people you have to rescue or defend come out unscathed, because this is a realistic game, in SWAT 4, like in real life, a bullet kills.
The SWAT team is one of the best prepared units to resolve special conflicts, like armed robberies with hostages in which dialogue has failed or even taking a building in which a terrorist group has barricaded itself. Your mission will be to have the minimum amount of losses with the great quantity of weapons that you will have at your disposal. Your task won't be simple, if you take into account that SWAT 4 is one of the most accurate realistic action games around. This game's development team even included real SWAT agents, and this has established a realistic setting that will be practically unsurmountable.
This demo only allows us to play one level of the single player campaign, but it includes a quick editor to create our own games.
