Chain Reaction is an online multiplayer gameplay mode that appears in the multiplayer component of Uncharted 2: Among Thieves.
In Chain Reaction there are five capture zones on the map, numbered one to five. One team begins at the first zone, while the other begins at the fifth zone. The teams must capture the zones in numerical order; ascending for the team that begins at zone one, and descending for the team that begins at zone five. Players capture zones by standing in them and defending them from any opposing players for a period of time, until they are in their team's control. The team that captures all five zones are declared the winners. Alternatively, if the 20-minute time limit expires before either team has captured all five zones, the game is declared a tie.
Chain Reaction first appeared in the multiplayer component of Uncharted 2: Among Thieves. Its inclusion in the game was confirmed when it was revealed as one of four gameplay modes available in the public multiplayer demo of Uncharted 2: Among Thieves.
