Master Chief: Isolation

Play the whole of Alien: Isolation's story as Halo 4's Master Chief.

You wake on the Torrens, board the Sevastopol, and stalk through its corridors — but the person doing it is Spartan-117, and the arsenal in your hands is Halo's.

What this mod does

• You are Master Chief. The player is named and addressed as Chief throughout the game's text.
• Halo's arsenal. Alien: Isolation's weapons take Halo 4 names and stats, read from your own Halo: The Master Chief Collection install.
• Plenty of ammo. Ammunition pick-ups are generous on every level.
• The Alien has HP. It can be wounded, driven off and dropped — and the game's own logic brings it back later.

What you need

• Alien: Isolation (the game you play)
• Halo: The Master Chief Collection, with Halo 4 installed — its weapon names are read from your copy

How it works

Nothing from either game ships in this download. On the first Play, a small patcher reads your own Alien: Isolation data and your own Halo 4 data, builds the changes locally, and backs up every file it touches. No game content is redistributed.

Honest notes

• Master Chief's body model cannot be converted from Halo's engine into this one, so he is Chief by name, text, HUD and (later) audio rather than a swapped model.
• The Alien's health pool is finite now, but whether every weapon wounds it is being tested; if the engine rejects projectile damage the rest of the mod still stands.

A mashup of Alien: Isolation (Creative Assembly / Sega) and Halo 4 (343 Industries / Xbox Game Studios).
