The Nine Tailed Fox Mod is a popular Game Mod of SCP – Containment Breach, based off of the SCP Foundation mythos.
Rather than playing as a defenseless Survival Horror protagonist making your way through hell on earth, you control the Clean Up Crew for the hell on earth - MTF unit Nine-Tailed Fox. Armed with a P90, you and two of your fellow elite soldiers march into a containment facility to gun down the escaped Class-D's and recontain the escaped SCPs.
No relation to the Asian Fox Spirit trope.
The game provides examples of:
- Adaptation Expansion: Aside from just being a remake of Containment Breach with weapons, different NPCs, and a different spawn point, the facility is much larger and has a massive variety of new rooms and SCPs.
- Artificial Stupidity / Luck-Based Mission: You're probably gonna get trapped by your teammates idling in the doorways of dead-ends several time per playthrough, making major progress almost impossible without cheats.
- Bottomless Magazines: Not you, but your friends do, as do the Class-D's.
- Bulletproof Vest: Your health is measured by the state of your kevlar vest.
- Commanding Coolness: The MTF operative you're playing as in question is apparently the Commander of Foxtrot Unit 1, the first unit of the Nine-Tailed-Fox. Referred as such in death messages whenever you're killed and your body isn't destroyed and/or hidden.
- Drugs Are Good: While smoking 420-J doesn't technically heal you, it clears up your vision and limp, so it can really improve your combat and navigation performance after getting roughed up.
- Elaborate Underground Base / Secret Government Warehouse: It's an SCP Facility, what did you expect?
- Elite Mook: All the MTFs are these to the Foundation, highly trained and loyal soldiers that aren't nearly as expendable as D-Classes.
- Featureless Protagonist: Unlike most examples, your Player Character actually can optionally talk via his soundboard, but otherwise has no personality, characterization, and is nothing but a floating pair of arms.
- First-Person Ghost
- Gas Mask Mooks: Unique in that you are one and fight alongside some, rather than being hunted by them, for once.
- You can also subvert this by simply taking off your gas-mask, although it doesn't really do any harm and you have it on by default.
- Heroic Mime: Averted, you have a soundboard of things for your character to say to direct your team.
- Hero of Another Story: Instead of being Villain Protagonist D-9341, you're the solid neutral MTF who hunts his kind down.
- Hyper-Competent Sidekick: The most pragmatic way of dealing with D's is to just have your two friends deal with it, as they're durable and have Bottomless Magazines.
- Man on Fire: SCP-457, The Burning Man, obviously.
- The Many Deaths of You: Like in the original game. Struck by a Tesla gate, mutilating yourself in 914, kidnapped and mangled by 106, getting your neck snapped by 173, turned to a pile of charred flesh by 457, gunned down by rabid Class-D's, looking at 096, etc.
- Mooks: The Class-D's are extremely common enemies to face and easy to take down, but are still deadly since they're all armed with guns.
- Nigh-Invulnerability: Even when you're finally armed to the teeth, 106 (and 457) is still an unstoppable killing machine. Luckily the Tesla gates can temporarily disable him.
- Ominous Walk: 106 and 457 take their time while chasing you.
- One Bullet Clips: Averted, like in Cry of Fear. Reloading is completely realistic in the mod, so say you have half a magazine and reload, you just permanently lost all of the bullets in that magazine.
- One-Hit Kill / Neck Snap: 173.
- 457 is also a one-hit-killer too.
- Palette Swap: 457 is almost identical to 106, both gameplay-wise and model-wise.
- Player Character: The Swedish-accented Nine-Tailed Fox soldier you control, and the supposed leader of the Power Trio.
- Power Trio: The game follows a three-man Clean Up Crew.
- Skeleton Key: The player no longer has to go around scavenging for keycards and upgrading them with 914 as in the original. Now they spawn with a level five that can open almost any door.
- Sprint Meter: Just as in Containment Breach, there's one for your stamina and one for blinking.
- Villain Protagonist: Downplayed. The MTF squads aren't really villainous by many means, they're just prominent antagonists in the original game and you're now in control of them.
- Zombie Apocalypse: There's a tiny one ravaging the deepest levels of the facility, so there's a few riot-armored SCP-008 infectees shambling around.
