When thrown, a tactical nuclear missile will be launched from the Yangtze which will land where the beacon was thrown. This does not work in tight spaces, deep quarries or inside buildings. The beacon is thrown at a speed faster than any other thrown weapon.
The nukes will not come from a vertical dive, rather the nuke will come at about a 60 degree dive from a random direction. If the beacon is used in an open area with buildings nearby, there is a chance the nuke will hit the roof of a building or a tree.
The explosion will be similar to a mini nuke in terms of blast radius and damage.
The beacon can be reverse-pickpocketed into the inventory of an enemy and still work, however only one beacon can be active while in the enemy's inventory.
The tactical nuke uses a 'completed' version of the same model used for the missile found in the Yangtze containing the Warhead. The model found on the Yangtze only has the top, curved portion of the missile modeled, while the tactical nuke has the full length of the missile modeled.
