A counter at the top of the screen indicates how many enemies remain alive. Once the setup time runs out or if a majority of players vote to skip it, the first wave will begin, with a large group of enemies spawning around the outer edge of the play area, who will then assault the area and try to kill both the players and their AI allies. If all AI allies die, the game will end with "Overrun" ending, even if the players successfully complete all waves. Every time an AI ally dies, a prompt will appear on screen showing ho many of them remain. Injured AI allies can be healed by interacting with them between waves. These AI allies are armed and will assist the player(s) by shooting enemies on sight but can also be injured and killed by said enemies.

At later waves, Maxim Guns will also become available for use.Īdditionally, there are a total of 10 AI allies spread throughout the map that the player(s) can interact with to make them follow the player and instructed to set up defensive positions in various places. There are also explosive crates and -boxes spread about which can be detonated by both players and enemies. Ammo crates restock at the end of each wave. These items can be picked up once and, with the exception of ammo crates, will not replenish, so it is strongly advise for all players to be well-stocked on both ammo and equipment before launching Call to Arms.

Scattered throughout the map are various weapons, ammo crates and healing items for the player(s) to use. When initially spawning in, all players will retain whatever weapons and equipment they had equipped prior to launching the game mode and will be given 5 minutes to prepare for the coming onslaught. Five locations are currently available: Blackwater, Fort Mercer, Valentine, Strawberry, and MacFarlane's Ranch. In Call to Arms, up to four players are tasked with defending a town or settlement from 10 waves of incoming enemies by killing them while keeping both themselves and their allies alive. After this, the game mode can be launched at any time by selecting the associated telegram in the Satchel. In order to gain access to Call to Arms, one must either check their Camp Lockbox or go to the nearest Post Office to find a telegram named "Call to Arms" from a person simply referred to as "J".
