Faster Kain

Faster Kain is a small executable patcher for the PC/GOG release of Blood Omen: Legacy of Kain.

It makes normal Kain — and mist form — move at the same speed as wolf-form Kain. The wolf speed is already a real, shipped game movement speed, so the patch should in theory avoid sequence breaks caused by values outside the game's normal range.

No game files are included. This mod patches your local Kain.exe.

What It Changes

• Normal Kain movement speed: 0x21C -> 0x438
• Mist-form movement speed: 0x1A4 -> 0x438
• Wolf-form Kain movement speed is already 0x438
• Two reset paths are hooked so the faster speed works immediately on load, before shapeshifting
• Disguise form also moves at the boosted speed: it reuses normal Kain's default movement-speed value, which this patch already raises, so no separate edit is needed
• Bat form (the fast-travel form) has no walking speed of its own and is unaffected
• Mana drain is not changed

Install

1. Close Blood Omen if it is running.
2. Copy the FasterKain folder into your Blood Omen install folder, next to Kain.exe.
3. Double-click Install Faster Kain.bat.

Or run this from PowerShell:

cd "C:\Program Files (x86)\GOG Galaxy\Games\Blood Omen\FasterKain"
powershell -ExecutionPolicy Bypass -File .\FasterKain.ps1 install

If your game is somewhere else:

powershell -ExecutionPolicy Bypass -File .\FasterKain.ps1 install -GameDir "D:\Games\Blood Omen"

The installer creates a backup named:

Kain.exe.faster-kain-backup

Verify

Double-click Verify Faster Kain.bat, or run:

powershell -ExecutionPolicy Bypass -File .\FasterKain.ps1 verify

Uninstall

Close the game, then run:

Double-click Uninstall Faster Kain.bat, or run:

powershell -ExecutionPolicy Bypass -File .\FasterKain.ps1 uninstall

If the installer backup exists, uninstall restores it. If no backup exists but the executable exactly matches Faster Kain's installed patch bytes, the script reverses the patch byte-for-byte.

Compatibility

Tested against the GOG/Verok PC release of Blood Omen. Other executables may not match the expected byte patterns; in that case, the patcher stops instead of guessing.

The mod should be compatible with anything that does not modify the same movement-speed constants or the two reset paths used by this patch.

Source

The mod is the PowerShell patcher itself. It is intentionally small and readable so the exact byte changes can be audited.

Build / Package From Source

No compiler is required. Faster Kain is a PowerShell patcher plus three batch-file wrappers.
