Customizing Mystery Box Weapons

Introduction

Nazi Zombies: Portable gives level creators the ability to customize what weapons exist in the Mystery Box. They have full-range of every non-Pack-A-Punch variant in the game. This is done via the MBOX2 file format.

MBOX2 files are created by the creator, placed in nzp/maps/ with the name mapname.mb2, substituting mapname with the same file name as the level .BSP.

Here is an example file that simply disables the Ray Gun and Wunderwaffe DG-2 from appearing in the Mystery Box:

nzp_mbox2

deny:
    ray_gun
    wunderwaffe

File Header

All MBOX2 files must begin with the string “nzp_mbox2”. This is done to ensure validity of the file. Nazi Zombies: Portable will not allow a level to load if it contains an MBOX2 file that does not meet this requirement, and report the issue to the developer console.

Allow vs. Deny

MBOX2 has two modes: “allow” and “deny”. Provided the allow command, all weapons listed will appear in the Mystery Box, and those not listed will automatically be excluded. Similarly when deny is used, all weapons will be included aside from the entries listed.

MBOX2 only supports one command, it is recommended to use the command that has the shortest number of entries to decrease loading time for low powered platforms.

Weapon Names

Eligible weapon names are provided via the Weapon IDs documentation entry. If a weapon is listed that is not recognized by the game, the level will not be allowed to load, and the problematic weapon will be reported to the developer console.

Backwards Compatibility

Nazi Zombies: Portable previously primarily utilized the MBOX 1.0 format, which was a string-binary list of hard-coded weapon order status. This format is still supported internally, meaning levels that previously utilized it will still function as intended. Additionally, while not recommended, it can still be utilized for new content. It uses the .mbox file extension.

Weapon Order

MBOX 1.0 files used a hard coded weapon order, that differs from the standard internal Weapon IDs used by Nazi Zombies: Portable. The MBOX 1.0-exclusive listing follows:
