- "Capture points to revive fallen teammates. Taking all points will win the round."
- — In-game description
There are three flags around the map, similar to Domination. If one is killed, they will go into Spectator mode. They will only respawn when a new flag is secured by their team. Securing all 3 flags results in an automatic win of that round for the corresponding team. Similarly to Search and Destroy/Rescue, a team will lose if all of their teammates are killed.
The first team to get 4 points (again, mirroring Search and Destroy/Rescue) wins the game. Overtime can be activated in this game mode, and Intermissions are active.
As of the May 30th playlist update, Reinforce is a playable game mode in the Core Playlist.
- This game mode was initially allowed in Private Matches only.
- Originally, capturing a flag awarded the players 1500 XP. However, in a later update, this was reduced to 750 XP.
