Backup is a game mechanic that allows the player to call for reinforcements to assist in battle. Arrival of Backup will take 20 seconds, and upon arrival, four MCP officers will get out of either a Subaru BRAT, Chevy El Camino, or a Chevy Corvan. One of them will have an M1887 or Remington 870, one will have an M16 or AKS74U, one will have an RPD, and one will have dual TEC-9s. The cooldown time for backup is one minute.

Backup is not available during missions or side missions, due to the fact that most of the time, the player will already be assisted by much more than four allies anyway.
