Fallout: New Vegas: Old World Blues Tips - Big MT Prep Guide

Fallout: New Vegas: Old World Blues is DLC for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks. It sends the Courier to Big MT, adds new enemies and gear, raises the level cap, and makes The Sink your main DLC base.

Content warning: Old World Blues has Mature 17+ content including blood and gore, intense violence, strong language, use of drugs, and sexual content. This guide stays non-graphic and focuses on play.

Spoiler note: This is a spoiler-light preparation and survival guide. It avoids exact quest routes, endings, skill checks, perk/weapon locations, and build optimization.

This guide covers Old World Blues itself, not the base Fallout: New Vegas campaign, not Dead Money, Honest Hearts, Lonesome Road, Courier’s Stash, or Gun Runners’ Arsenal.

Essential Tips

1. Confirm You Are Playing Old World Blues

The DLC is not a standalone game or the full New Vegas campaign.

Old World Blues requires Fallout: New Vegas. It is one add-on among several, so do not mix it up with base Mojave quests, Dead Money’s casino structure, Honest Hearts’ Zion trip, Lonesome Road’s Divide, Courier’s Stash gear packs, or Gun Runners’ Arsenal equipment expansion.

2. Treat Level 15 as a Floor, Not a Comfort Zone

The recommendation does not mean every Courier will feel ready.

A level 15+ recommendation is common, but Old World Blues can feel noticeably harder than the base game or Honest Hearts. Enter when your core combat, healing, weapon upkeep, and inventory habits are already stable.

3. Pack Before You Trigger the DLC

Old World Blues lets you keep your gear.

Unlike some New Vegas DLC structures, this add-on does not strip your equipment at the start. Bring enough healing, ammo, repair support, food or Hardcore supplies if relevant, and backup weapons before you commit to Big MT.

4. Do Not Plan Around Normal Companions

Your usual followers are not your safety net here.

Old World Blues does not let normal companions accompany the Courier to the new location. Build your prep around self-sufficiency: healing, damage options, armor condition, carry weight, and manual saves.

5. Use The Sink as Your Operating Base

It is more than a joke room.

The Sink is player housing in Big MT with storage, workbench support, reloading support, an Auto-Doc, a merchant/repairer, and upgradeable appliances. Return to it often instead of trying to solve the whole crater from your backpack.

6. Keep Healing Pressure Under Control

Stimpaks and vendor access can feel tighter than expected.

Stimpaks and vendor access can feel limited in Big MT. Use the Auto-Doc when returning to base makes sense, and do not spend every healing item on avoidable fights in the open crater.

7. Carry Flexible Damage Options

Big MT throws different enemy types at you.

The DLC includes enemies such as Lobotomites, robot scorpions, and other experiments. Avoid entering with one fragile weapon plan or one ammo pool. A practical loadout has answers for armored targets, groups, robots, and emergency close-range pressure.

8. Explore Like Big MT Is a Zone, Not a Hallway

The crater is open and returnable.

Old World Blues is an explorable DLC space, and you can return after completion. Make short loops, learn landmarks, mark useful facilities mentally, and revisit The Sink between pushes.

9. Upgrade Sink Functions as You Find Them

Base improvements turn clutter into resources.

The Sink’s appliances become more useful as you recover their related upgrades. Without listing exact locations, the practical habit is simple: when you find a personality holotape or upgrade clue, bring it home and check what changed.

10. Save Before Major Decisions

Leave endings and branch planning for a spoiler-marked guide.

This first guide avoids exact story outcomes. Make manual saves before obvious major commitments, dialogue-heavy turning points, unusual experiments, and expensive inventory decisions.

Before You Enter Big MT

Prep Item	What to Check
DLC scope	Old World Blues is installed and selected, not another add-on
Character level	Level 15+ is the common recommendation, but comfort matters more
Healing	Bring stimpaks and other recovery options you already trust
Weapons	Carry a flexible mix rather than one ammo-dependent plan
Repairs	Bring enough support to keep important gear usable
Carry weight	Leave room for new DLC loot and tech
Companions	Do not expect normal followers to enter Big MT with you
Saves	Make a manual save before starting and before major commitments

Using The Sink

Sink Feature	How to Think About It
Storage	Treat it as your safe DLC inventory hub
Auto-Doc	Use it to recover between hard pushes instead of draining all supplies
Merchant/repairer	Check it when selling, repairing, or rearming between loops
Workbench	Convert useful parts and keep repair/crafting options available
Reloading bench	Support ammo planning if your character uses it
Appliances	Upgrade them when you recover related holotapes or functions
Home-base loop	Explore, return, repair, sort inventory, heal, then push farther

Combat and Supply Habits

1. Do not spend rare healing on every mistake - retreat, break line of sight, or return to The Sink when the fight is not worth the cost.

2. Keep one emergency weapon ready - Big MT can punish slow reloads, empty ammo pools, or damaged favorite weapons.

3. Watch robot fights carefully - robot scorpions and other machines can turn small overextensions into expensive healing checks.

4. Loot for function, not just caps - repair parts, ammo, medical supplies, and crafting materials matter more here than hauling every heavy item.

5. Use base visits as resets - the Auto-Doc, merchant/repairer, workbench, reloading bench, and storage make short exploration loops safer.

6. Do not force every fight immediately - the DLC is open enough that retreating, restocking, and coming back is often smarter than draining all supplies.

7. Expect the tone to be strange - Old World Blues uses dark sci-fi comedy and B-movie energy, but the fights and resource pressure still matter.

Common Mistakes to Avoid

1. Do not enter just because you reached level 15 - make sure your gear, healing, and combat habits are ready too.

2. Do not leave supplies behind because you expect a gear strip - Old World Blues lets you bring your equipment.

3. Do not rely on normal companions - prepare as if every hard fight is yours to solve.

4. Do not ignore The Sink after the intro - it is your safest base for healing, storage, repairs, and upgrades.

5. Do not burn through stimpaks while standing near a base option - return, heal, and reorganize when the route allows it.

6. Do not carry only one damage plan - Big MT mixes enemy types and can punish narrow loadouts.

7. Do not follow Dead Money, Honest Hearts, or Lonesome Road advice here - each New Vegas DLC has different rules and structure.

8. Do not turn every discovery into a wiki lookup - save exact routes, weapon locations, skill checks, and endings for a spoiler-marked cleanup pass.

9. Do not make major dialogue or experiment decisions without a manual save - the first run is better when you preserve options.
