Hell Let Loose: Vietnam keybinds and controller customisation
A dated record of what the publisher actually changed about keybinds and mouse remapping, plus the right-mouse-button report that support has escalated.
Answer: Keys can be reassigned since Patch 1.3, bindings only save when you press Apply since Patch 1.4, and mouse-input remapping was improved in 1.4. As of Community Feedback #8 on 15 October 2026 the status is still "Under Investigation", and the right-mouse-button report has been passed to the team.
Short answer
Key rebinding is a supported feature, but the publisher has been working through it for months and still describes it as "Under Investigation". The most recent public statement on 15 October 2026 says they are "continuing to address keyboard rebinding issues, with additional fixes being worked on for Update 2". A separate report — right mouse button used to move forward turning into aim-and-move — has been passed to the team by support, without a fix named.
The thread was listed and read on 21 October 2026; it is no longer listed on the Steam boards, so this answer records the exchange as it stood at that reading and does not claim the thread is still open.
What has actually changed, by date
| Date | Official post | What it says about input |
|---|---|---|
| 21 Aug 2026 | Patch 1.2 | A wide range of UI, HUD, settings and keybinding issues resolved, including Tactical Map keybinding issues and duplicate keybind warnings. |
| 28 Aug 2026 | Patch 1.3 | A keybind already assigned to an action can be reassigned to another action, and the Exit Vehicle keybind is no longer hardcoded. |
| 3 Sep 2026 | Patch 1.4 | Keybindings now only save when you choose to Apply them; improved mouse input rebinding; resolved conflicting keybindings affecting Admin Controls. |
| 3 Sep 2026 | Community Feedback #3 | "Keybindings & Rebinding" — status Under Investigation, with improvements to remapping mouse inputs and remaining cases where keybindings behave incorrectly or fail to persist. |
| 10 Sep 2026 | Community Feedback #4 | Fully customisable controller remapping is technically possible but "requires a different approach to traditional keyboard and mouse rebinding". |
| 9 Oct 2026 | Community Feedback #7 | "Keybinds & Custom Controls" — status Under Investigation; the number of possible custom configurations means combinations can behave differently from the defaults. |
| 15 Oct 2026 | Community Feedback #8 | "We're also continuing to address keyboard rebinding issues, with additional fixes being worked on for Update 2." |
The right-mouse-button report
A player reported that using the right mouse button to move forward turns into aim-and-move and the character cannot run. Team17 support replied that they have already answered on the Hell Let Loose forums, asked which of the two games the issue affects, and that they "have also passed the issue regarding the right mouse button on to the team to look into further". No patch is named for it, so treat it as reported and escalated, not fixed.
Practical takeaways
- If you rebind, press Apply — since Patch 1.4 the bindings only save when you do.
- Mouse-button remapping is the part still in active work, and so is the right-mouse movement conflict. If you hit either, check the newest Community Feedback post before changing hardware.
- We have not tested the current keybind behaviour ourselves, and this page gives no key map, because the publisher publishes none.
