You're the undercover agent David Jones who's part of the secret agency IGI and in charge to protect the world from international terrorism.
IGI-2: Covert Strike starts where the first part ended. So, again, you have to fight for your own, infiltrate enemy bases, wander through huge outdoor and indoor levels, hack computers and find the best strategy to solve the mission. You could say: a sneaker-shooter!
Additionally, the game features multiplayer support where you can solve missions on special mp-maps.
The game was banned in China in 2004 for defamation of the country's character and its army. The game's protagonist "steals intelligence and conducts sabotage in China and shoots at China's soldiers while China's national flag and signs like 'China Aviation' pop up frequently". Gaming regulations in the country prohibit games "that hurt China's national dignity and interests".
