Contend is similar to the Capture game mode. In Contend, instead of each team having its own package and having to capture the other team's package, there is only one package in the centre of the map. Each team must fight to secure the package and take it back to their base. Once the package is captured, it respawns at the centre of the map again.
Just like Capture, vehicles are available to use in Contend. They can be useful for quick getaways once a player secures a package. The package can be destroyed if it is underwater.
