 # nobob-halflife-patch
-client.dll patch to remove view bobbing in Half Life
+A simple client.dll patch that removes the main forward/backward view bobbing in Half-Life.
+
+I started replaying Half-Life and could barely last 10 minutes before motion sickness kicked in. None of the launch options or mods helped, so I patched the client.dll myself. This removes the big “main” bob. The small side-to-side sway is still there for now, but I might patch that later.
+
+I couldn’t find any existing patch that does this, so here it is.
+
+## Installation
+
+**0.** Back up your original `client.dll` in case you want to revert.
+
+**1.** Replace the file here with the patched version:
+
+SteamLibrary\steamapps\common\Half-Life\valve\cl_dlls\
+
+**2.** Launch the game. The main view bobbing should now be gone.
