Handler notes

A maximum of 4 players can play the Zombies gamemode. To play Zombies select online, look for a match and select preferred map (on gamepad press the start button to select a map).

Have the other players search for the online match and once connected, each player should select ready up. The match should start shortly after the count down.

For multiplayer, launch your instances and proceed to have the first player host a combat training match. Once the match has loaded, press F2 or the start + select buttons simultaneously on your gamepad to connect the other instances.

To quickly restart your match press F3 or the start + Y buttons simultaneously on your gamepad.

If playing with more than 4 players, or multiple mouse and keyboard, you will need to i) lock input by pressing the end key and ii) assign gamepads first, followed by mouse and keyboard in sequential order, if not menus for the gamepad instances will not work properly.

To play multiplayer over LAN, be sure to change the player ID, and to select the last digits of the host IP - this can be done through the game launch options in Nucleus.

Menu support has been added for gamepads, use the dpad to scroll through the options, and the start/select buttons to select or move to the previous option. Aim assist only works for Zombies.

The hotkey exes (F2 host, F2 Guest, start, prompt etc.) may be blocked or flagged by window defender as potential viruses, but can guarantee they are nothing but false positives as they were created by Perseveruz with Autoit.
