Key Mapping and Exclusive Fullscreen Support

Battle Marine · published 12 Oct 2026, 22:50 UTC · build 25877267

All newsPlayers around this dateRead on Steam

This update adds two new features:

  1. KEY MAPPING in CONFIG

  2. A launch option (-e) for exclusive fullscreen mode (Windows only)

1. KEY MAPPING

We have added KEY MAPPING to the CONFIG menu on the title screen.

Select KEY MAPPING to customize your keyboard key bindings.

Previously, changing key bindings required editing the config.json file. You can now make these changes directly in the game.

Editing config.json is still supported after this update.

2. Exclusive Fullscreen Mode (Windows Only)

The Windows version normally runs in borderless fullscreen mode.

Some users have reported severe slowdowns when using Steam Game Recording in this display mode. We have confirmed that launching the game in Direct3D exclusive fullscreen mode improves this issue.

This update adds an option to launch the game in exclusive fullscreen mode. In your Steam Library, open the game's Properties, select General, and enter -e in Launch Options.

The game includes intentional slowdown as a visual effect. The issue described here is different: the slowdown is accompanied by audio stuttering. Whether the background music continues playing without interruption can help you tell the difference.
