To change hammer modes in Mini War on Roblox, open the weapon while you’re in-game and look for the mode-switch control tied to the hammer’s input, then cycle through the available modes until it changes. Public guides for Mini War currently point to the game’s in-match controls and settings menu for customization, but I couldn’t verify a hammer-specific keybind from the available sources.

What to try

  • Equip the hammer first.
  • Check for a mode indicator on the HUD or near your hotbar.
  • Try the usual Roblox weapon-switch inputs, such as the mouse wheel, number keys, or a dedicated mode key if the item shows one.
  • Open the in-game settings gear if the hammer has a control option listed there.

If it still won’t change

  • The hammer may only switch modes after a certain progression unlock.
  • Some weapons in Roblox games use a click, key press, or secondary attack rather than a visible menu.
  • If the game updated recently, controls may have changed from older guides or videos.

Fast check

  1. Equip hammer.
  2. Look for a mode label or icon.
  3. Press the secondary interaction key.
  4. Open settings and inspect control options.
  5. Rejoin the server if the UI does not refresh.

TL;DR: Equip the hammer, look for a mode prompt or keybind, and check the in-game settings menu; the currently available public info confirms Mini War has customizable in-game controls, but not a verified hammer-mode shortcut.
