Time Crisis 4

 is a 2006 action film about an army of terrorists who have taken over and invaded. The film begins in California, where intelligence officials from both the US Military and the VSSE learn about a top secret weapon targeted for terrorists' smuggling. William Rush infiltrates a pier to gather more information, and finds that the enemy has already acquired the insect-like weapons (codenamed "Terror Bite"). After being told by Elizabeth Conway about an information leak incident at the airport, Rush then heads to the airport to rescue VSSE agents Giorgio Bruno and Evan Bernard, and advance further to subdue the weapons smugglers. After defeating all of the enemies, they discover U.S. Army dog tags on the enemies' bodies and realize that the terrorists are soldiers like Rush. After Rush found out about the terrorists' identities (The Special Biological Weapons Research Unit, a.k.a. the Hamlin Battalion), he was forced to thwart the enemies' plot to destroy a dam alone. After having to put up with the battalion's destruction at the dam, Rush, Giorgio, and Evan fly to a secluded bio-weapons research facility in Wyoming only to discover the Battalion's alleged smuggling at San Francisco was actually an act of treason. Elizabeth Conway then tells the men that the Hamlin Battalion has hiijacked Buckley Air Force Base near Aurora, Colorado, prompting the men to rush to the AFB. As William, Giorgio, and Evan invade the AFB from the outside, a couple of Unmanned Combat Air Vehicles (UCAVs) departed the base without warning. The mercenary Wild Dog also appears and attacks the agents, forcing the agents to defend themselves. After they land their helicopter safely, they pursue Wild Dog into the base and defeat him, ending with Wild Dog detonating himself for the third time. A light gun arcade game adaption based on the film was developed by Namco, and was released for the arcade and the Sony Playstation 2 (which is compatible with the "Guncon" light gun).
