Grand Theft Auto is one of the most popular games ever to hit the game world, and with the new missions and plots introduced in the online version, it only gets better at showing all the great.
What Happens When You Complete All IAA Missions- GTA Online
The International Affairs Agency, or the IAA as they are referred to in the game, is a governmental intelligence agency which, at the time of GTA online, gave missions like the Doomsday Heist to players to play through in 2017. The most recent event or mission was for players to assume the identity of a newly recruited IAA agent to quell a criminal conspiracy in south San Andreas.
Go to a Bunker
After a player completes all 6 IAA missions, they are led to go to a Bunker/Silo in the final mission to find some fuses, turn the bunker on, connect to some servers and kill all the juggernauts in the bunker and escape the guards. A helicopter containing Hertz’s former followers will fly in an attempt to put a stop to matters after players have managed to leave the silo.
Depart Mount Chiliad
Players must depart Mount Chiliad after taking out the helicopter. They can do this by leaping from a building and opening a parachute. Attack helicopters, though, will be pursuing. The IAA facility depicted on the map must be reached after players are far enough away from Mount Chiliad to be safe.
