Syphone Filter 3 - shooter created with the support of Sony.
Gabriel Logan - the protagonist of all parts of the stealth-action. After some events secretary Vincent Hadden trying to accuse him of crimes against the state and speak before Congress. To justify and stay on Logan freedom and its allies need to remember all the things which they worked the last few years and tell Congress what's what.
The plot is divided into two parts. First - memories of heroes of the game. You will go to Costa Rica, where Logan will destroy the helicopters, to produce the necessary state of plant samples, to avenge the fallen allies and destroy smuggled weapons. In the other part we will work in real time.
Compared with the last part of the game has improved markedly. Stealth missions became smaller, a little more action. Added new weapons and special equipment, such as X-ray target. Artificial intelligence has become smarter - now enemies have leaed to analyze the actions of the player and decide to fight or hide.
