What it does

This mod adds couch co-op to over the hill. Plug in two controllers, start split-screen from the MODS menu, and a second player drives their own truck on their own half of the screen with their own camera, map, winch and save.

It also adds a MODS menu with car cheats, unlocks, time and weather controls, and a pile of fun stuff like flying cars, raining cars and meteor showers. If you'd rather type, there are 36 cheat codes too. Everything runs in your own game: solo, or when you're the host.

Split-screen for two

  • Top and bottom, or side by side. Switch any time from MODS > SPLIT-SCREEN.
  • Player 2 gets their own truck, camera, HUD, radial menu, map and map pin.
  • Player 2 has their own save by default: coins, garage, explored map, points of interest, cabins and trails.
  • Both players can use the mechanic, trails, portals and camping. Portals and camping need both trucks there.
  • Player 2 can winch onto trees, rocks and player 1's truck, and the other way round.
  • Each player gets their own MODS menu in their own half of the screen.

MODS menu

  • Open it with F8 or Pause > MODS. Five tabs: Cheats, Unlocks, World, Split-screen and Fun.
  • Cheats: invincible, turbo engine, mountain goat grip, mega traction, moon gravity, super brakes, and an engine that never floods.
  • Unlocks: coins, cars, liveries, cosmetics, upgrades, tool slots, areas and cabins, for either player's save. These are permanent, so the menu asks you to press twice.
  • World: reveal the map, teleport to your pin or the merchant, set the time of day, freeze the clock, northern lights, and trees drawn further away.
  • Fun: flying cars, driving on water, nitro, car jump, wheels only, black ice, raining cars, meteor showers, chaos mode, and game speed from 0.25x to 2x.
All 36 cheat codes

Press F9 in the world, type a code and press Enter. Codes always apply to player 1. The horn is Z on the keyboard or a left-stick click on a controller.

Requirements

Game
over the hill on Steam, Windows version
Windows
Windows 10 or 11, 64-bit
Controllers
Two controllers connected for split-screen. Player 2 has to use one. Player 1 can play on the other or on keyboard and mouse, but both controllers still need to be plugged in.
Included
BepInEx 6.0.0-be.793 (IL2CPP) and the .NET 6.0.7 runtime, put in the game folder. Nothing else to install.
Admin rights
Not needed, unless your game folder is write-protected. Then the installer offers to restart as administrator.
Online
Cheats and split-screen work in your own game only: solo, or when you're the host.
Tested on
Steam build 26326013. The installer tells you if your game has updated since; most things usually keep working.

Screenshots

All shots in split-screen at 1920x1080. Player 1 is the green Boar, player 2 the white and red TrailBurner.

Install

  1. Close the game.
  2. Run the Setup.exe from the download button. If Windows says Windows protected your PC, click More info, then Run anyway. The installer isn't code-signed, so Windows doesn't know it yet.
  3. It finds your Steam copy by itself. Click Install mods. If it can't find the game, click Change... and pick the folder with over the hill.exe in it (in Steam: right-click the game > Manage > Browse local files).
  4. Start the game from Steam as usual. The first start takes 1 to 3 minutes and the window may stay black while the mod loader sets itself up. After that it starts normally.
  5. In the world, press F8 or open Pause > MODS. For split-screen: connect two controllers, go to MODS > SPLIT-SCREEN > Start, and player 2 presses A.

Got an older version? Close the game, run the new Setup.exe and click Update to .... Your mod settings and both players' saves are kept.

Uninstall

  1. Close the game.
  2. Run the Setup.exe again (download it here if you deleted it) and click Uninstall.
  3. Confirm. Your saves stay, including player 2's.

This removes winhttp.dll, doorstop_config.ini, .doorstop_version, the dotnet folder and the mod. If no other BepInEx mods are left, the whole BepInEx folder goes too.

Removing it by hand

If the Setup.exe won't run: close the game, open the game folder and delete winhttp.dll, doorstop_config.ini, .doorstop_version, dotnet and BepInEx. Your saves live in Documents, not in the game folder.

Troubleshooting

Windows says "Windows protected your PC"

The installer isn't code-signed, so SmartScreen doesn't recognise it. Click More info, then Run anyway. If you want to check the file first, compare its SHA-256 with the one under the download button.

The installer can't find the game

Click Change... and pick the folder that has over the hill.exe in it. In Steam, right-click over the hill > Manage > Browse local files to open that folder.

The game window stays black after installing

On the first start after installing, and after a game update, the mod loader sets itself up. That takes 1 to 3 minutes and the window can stay black the whole time. Give it a few minutes. Later starts are normal.

"Split-screen needs 2 controllers connected"

Both controllers have to be connected before you press Start, even if player 1 plays on keyboard and mouse. You also need to be out in the world (not the staging screen) and in your own game, not someone else's online game.

A message says some game hooks didn't load

The game has updated since this version was made. Most things usually keep working; only the parts tied to the changed game code stop. Check back here for a newer version. The installer also tells you when your game build differs from the one the mod was made for.

"Please close over the hill first"

The game is still running. Close it fully (check Task Manager) and run the installer again.

Something else is wrong

The mod loader writes a log to BepInEx\LogOutput.log in the game folder, and it usually names the part that failed. Running the Setup.exe again and clicking Repair writes every mod file again.
