Widely considered the high point of the modern "Survivor" trilogy, Rise of the Tomb Raider

(2015) successfully blends blockbuster action with more traditional exploration elements.

Gameplay & Exploration: It significantly increases the number of "Challenge Tombs," which feature intricate physics-based puzzles that were largely missing from the 2013 reboot. The game uses a "Metroidvania" style, where new tools allow you to backtrack and unlock secrets in previously visited areas.

Combat & Stealth: Combat is versatile, allowing for both "guns blazing" and improved stealth tactics. Lara can now craft items like molotovs and smoke bombs on the fly using scavenged materials.

Story & Characters: Set mainly in the harsh Siberian wilderness, the plot follows Lara as she seeks the "Divine Source" to prove her late father's research was correct. While the narrative is praised for making Lara a more confident hero, critics often find the supporting cast and villains somewhat predictable.

Visuals: Even years after release, the game is visually stunning, featuring highly detailed character models, realistic snow effects, and expansive environments. Community Perspectives

“Rise was amazing. A big step up from the first title, definitely better than Shadow, which I also enjoyed but the story was weaker.” Reddit · r/patientgamers · 2 years ago Corrupted game files : Corruption can occur due

“It is a good game, it just isn't a Tomb Raider game like the classics were. Game is quite linear, it just feels non-linear due to the many collectibles.” Reddit · r/TombRaider · 4 years ago

Verdict: A must-play for action-adventure fans. It offers about 13-15 hours for the main story and up to 40 hours for completionists.

Part 1: What is BIGFILE.000?

Before diving into fixes, it helps to understand why this file matters.

bigfile.000 is not a standard save file or configuration text file. It is a container archive—think of it as a massive digital suitcase. Inside this suitcase, the game stores:

  • 3D character models
  • Environment textures (snow, rocks, wood)
  • Audio dialogue files
  • Level geometry for Syria, Siberia, and the Geothermal Valley
  • The game’s manifest (a master list telling the game where everything is located)

The "top level asset manifest" mentioned in the error is essentially the table of contents for that suitcase. If the game opens the suitcase (bigfile.000) and finds that the table of contents is the wrong version, corrupt, or missing, it immediately crashes with this error.

Solution 1: Verify Game File Integrity (Steam/Epic)

This is the first and most effective fix for 70% of users. Verification scans every bigfile and redownloads only the corrupted pieces.

For Steam:

  1. Open Steam and go to your Library.
  2. Right-click Rise of the Tomb Raider → Properties.
  3. Click Installed Files → Verify integrity of game files.
  4. Wait 5–10 minutes. Steam will report: "X files failed to validate and will be reacquired."
  5. Let it download the repair. Launch the game.

For Epic Games Store:

  1. Open Epic Launcher → Library.
  2. Click the three dots (...) under Rise of the Tomb Raider.
  3. Select Verify.

If you’re seeing the error message "Unable to open BIGFILE000.000.tiger" (or a similar variation like bigfile000.top) when trying to launch Rise of the Tomb Raider, you’re not alone.

By moving the game to a generic folder path (like D:\Games) or verifying the file cache, you should be able to resolve the issue and get Lara Croft back on her adventure.

4.5. Run Game as Administrator (Rarely fixes, but harmless)

Right-click RiseOfTheTombRaider.exe → Properties → Compatibility → Run this program as an administrator.

What if Nothing Works?

A small number of users have reported this error appearing after a Windows update changed how the game reads its archive headers. In that rare case:

  • Disable fullscreen optimizations in RoTTR.exe → Properties → Compatibility.

As a last resort, renaming bigfile.000.tiger to bigfile.000.old and then verifying game files forces a fresh download of that specific archive.
