GTFO is a hardcore 4-player co-op horror FPS set in a massive underground complex where your team is sent on dangerous expeditions to retrieve items from creature-infested depths. The game is designed around stealth, communication, and resource scarcity — you can't fight everything, and every bullet counts. Enemies called Sleepers stand dormant until disturbed by sound or light, and a single mistake can alert an entire room. With regularly rotating 'Rundown' content drops and some of the most intense co-op gameplay in any FPS, GTFO is the thinking person's Left 4 Dead.
GTFO features distinct areas with increasing difficulty. This guide covers every major location in progression order — what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.
Area Progression Order
| Order | Location | Difficulty | Key Rewards | Recommended Build |
|---|---|---|---|---|
| 1 | Rundown Levels | Tier A (beginner) to Tier E (expert) | Rundown completion, expedition-specific artifacts, bragging rights | Sentinel |
| 2 | Complex | Tier A-B expeditions | Basic resources, keycards, initial objective items | Sentinel |
| 3 | Mining Sector | Tier B-C expeditions | Mid-tier resources, progression keys, harder enemy variants | Scout |
| 4 | Floodways | Tier C-D expeditions | Unique enemy encounters, high-value objectives, challenging terrain | Scout |
| 5 | Datacenter | Tier D-E expeditions | Highest difficulty content, expedition completion achievements, endgame challenges | Scout |
Rundown Levels — Starting Area
GTFO's content rotates through 'Rundowns' — periodic content drops that replace all previous expeditions with new ones. Each Rundown has multiple tiers (A through E) of increasing difficulty. Current Rundown levels are always available, while past Rundowns can be accessed through the Alt Rundown system.
| Attribute | Detail |
|---|---|
| Difficulty | Tier A (beginner) to Tier E (expert) |
| Key Rewards | Rundown completion, expedition-specific artifacts, bragging rights |
| Recommended Build | Sentinel |
| Key Equipment | Assault Rifle |
What to Do Here
- Learn the basics of stealth mechanics — this is where you practice without heavy punishment.
- Collect starting resources and your first equipment upgrade.
- Clear all main content before moving to Complex.
- If you're struggling, read our beginner's guide.
Complex — Early Game
The starting area of most expeditions — a relatively well-lit facility section with standard Sleepers. The Complex teaches map reading, terminal usage, and basic stealth. Enemies here are predictable and rooms are manageable with careful play.
| Attribute | Detail |
|---|---|
| Difficulty | Tier A-B expeditions |
| Key Rewards | Basic resources, keycards, initial objective items |
| Recommended Build | Sentinel |
| Key Equipment | Assault Rifle |
What to Do Here
- Focus on mastering resource scarcity — it's critical from this point on.
- Farm for Assault Rifle if you don't have it yet.
- Complete all objectives for maximum rewards.
- Prepare for the difficulty spike in Mining Sector.
Mining Sector — Mid Game
Deeper into the facility where lighting decreases and enemy density increases. Mining Sector rooms are larger with more Sleepers and less cover. The darkness requires flashlight management (flashlights can wake Sleepers). Navigation becomes challenging in the labyrinthine mine shafts.
| Attribute | Detail |
|---|---|
| Difficulty | Tier B-C expeditions |
| Key Rewards | Mid-tier resources, progression keys, harder enemy variants |
| Recommended Build | Scout |
| Key Equipment | Assault Rifle |
What to Do Here
- This is the main skill check. Bring an optimized build.
- DMR becomes accessible here — prioritize getting it.
- Master terminal hacking for the boss encounters.
- Check our boss guide if you get stuck.
Floodways — Late Game
Partially flooded sections where water affects movement speed and visibility. The sound of wading through water can alert Sleepers, making stealth harder. Unique aquatic enemy variants appear here. The Floodways contain some of the most intense alarm defense sequences.
| Attribute | Detail |
|---|---|
| Difficulty | Tier C-D expeditions |
| Key Rewards | Unique enemy encounters, high-value objectives, challenging terrain |
| Recommended Build | Scout |
| Key Equipment | DMR |
What to Do Here
- Full build optimization is expected by this point.
- DMR should be your primary, fully upgraded.
- enemy alertness mastery starts mattering here.
- Farm resources for the push into Datacenter.
Datacenter — Endgame
The deepest facility sections with the highest enemy density and the most complex terminal puzzles. Datacenter expeditions require perfect team coordination and optimal resource management. Failed attempts here mean 30-60 minutes of progress lost. Only for experienced teams.
| Attribute | Detail |
|---|---|
| Difficulty | Tier D-E expeditions |
| Key Rewards | Highest difficulty content, expedition completion achievements, endgame challenges |
| Recommended Build | Scout |
| Key Equipment | DMR |
What to Do Here
- This is endgame. Best-in-slot gear and a perfected build are mandatory.
- See our boss guide for endgame fight strategies.
- The reward loop: clear content → upgrade → push harder content.
- Experiment with Support for variety once you've mastered the meta.
Exploration Tips
- Clear areas in order — Rundown Levels → Complex → Mining Sector → Floodways → Datacenter. Skipping areas means missing resources you'll need later.
- Check every corner — Hidden caches and secrets are often in non-obvious locations.
- Match your equipment — Some areas favor different equipment types.
- Read the walkthrough — Our walkthrough provides exact progression milestones for each area.
- Don't rush — Clearing an area fully gives more resources than speedrunning two areas.
