SWAT 4 is a tactical first-person shooter video game developed by Irrational Games.
SWAT 4 features a single-player campaign in which the player has to lead a police SWAT element through 13 missions.The game aims to have gameplay similar to real SWAT experience. For example, it encourages the use of non-lethal force to subdue and arrest subjects rather than incapacitating or killing them. In addition, players must follow strict protocol to ensure proper use of force. Players may not fire on suspects with lethal weapons unless the suspect points their firearm at a fellow officer or a civilian. Penalties are given for unauthorized use of force, injuries to hostages, officer incapacitation, and personal injury. On the higher difficulty levels, more points are required to pass the mission, with 100 being perfect. On the most difficult level, Elite, players need a 95/100 to pass, and will fail for killing even a single suspect, losing more than two team members without committing an infraction, or committing any infraction in addition to being injured.
SWAT 4 also features several multiplayer game modes, all of which are team-based: SWAT versus suspects. The multiplayer also includes various modes.
Teams gain points by arresting or killing members of the other team. The team which hits the score limit first or has the highest score when the round time ends wins.
A random member of the SWAT team is selected to be the VIP.
The suspects must arrest the VIP, hold him for two minutes and then execute him. The SWAT team must escort the VIP to an extraction point on the map. If the suspects kill the VIP without holding him for two minutes, SWAT wins. If a SWAT team member kills the VIP, suspects win.
Three to five bombs are placed throughout the map. The SWAT team must locate and disable them all within a time limit, if they fail to do so, suspects win.
This allows the player to play through the single-player missions with up to four other people taking the place of computer-controlled SWAT officers. In the expansion, Co-op can run on custom missions and with up to ten players per game, which can further be split into two completely separate teams (red and blue) with a leader each. This is not similar to single player teams where an element leader controls both teams.
