Reinforce game mode, a new mode Infinity Ward introduced a few weeks ago for Private match only on Ghosts, is now available to play in the Public Playlists. The mode is available on PS4, PS3, Xbox One, Xbox 360, and PC.

Reinforce is a round-based game mode that takes elements from Domination and Search and Rescue. There are three objective markers for teams to capture and respawns are disabled. If a team captures a point, they are “reinforced” and all dead teammates are allowed back into the round. There are multiple ways to win a round: Wipe out the entire enemy team, control two objective points when the time limit runs out, or capture all three flags for an instant victory. The first team to win four rounds wins the match.
