A containment breach was declared in the Aegis Research Facility, caused by a Class 4 or above UT of unknown type.

The Special Response Team is sent in as part of a contingency plan. You play as Specter 8 and must maintain radio contact at all time with Morpho, your operator.


This is a short horror adventure where you role-play as a hardened Spec Op making his way through the dark hell that became the underground facility.

10-103:NULL KELVIN is out!

is this supposed to be like scp

Where is the sound

how do i Bette floor 10 

Very nice. 

Simple yet thrilling.

that was so much fun :)



This game is absolutelly awesome

the mechanics, the combat, the lore, all well did

Keep doing awesome stuff

how do you get past floor 10 ive been trying for like 2-3 hours

(1 edit)

ok so i figured out how to escape the class five but when killing the third class four (i think its a class four) i die to the class five, what am i supposed to do here

Edit: so i got to the forth class four but once again the class five kills me after i kill the class four

Get gud

As soon as i kill last enemy on floor 10 it kills me.

bruh i cant get past lvl 10



how i thought it was made to be impossible


pay attention to the lights, when you kill the enemy on the way back to the elevator you came out of start  going left, took me a while to figure it out lol.

can you at least tell the ending to me

same im so close too

very cool

So this is MTF Nine Tailed Fox from SCP Containment Breach basically?

As soon as that FRB went off I turned and smashed the shoot button

Great game, I noticed there were alot of references(?) to the SCP Foundation which I like alot.

loved it


i won and died 2 many times in floor 10


nice game

Impressive !

el juego me gusto me dificulte mucho en pasarlo y tambi茅n me gusto 10-103:NULL KELVIN




bro hit that ^w^ 馃拃

This game was really cool. I'm a sucker for anything reminiscent of the SCP foundation and this game definitely hit that. The simple controls made this game easy to understand and play and really allowed me to appreciate all of Spectre-8's dialogue. He definitely isn't getting paid enough for this shit.

how do you do floor 8?

I REALLY loved this! While the first game in this series is fairly simple, it sets the tone and pace for something bigger which is exactly what Null Kelvin nails. Meeting all the different UTs in containment and the hint at this world's deeper lore was my favorite part. I hope that we eventually get a sequel/full fledged game! :)

Nice game! The "run from the static" blood on the wall made me instantly afraid of the flickering. Fear by sound was awesome. Some bugs: when playing with ultra wide-screen you can see beyond the dark mask, and sometimes even the corridor on the other side of the wall. Also the elevator go down even if you hit "up" on your keyboard.

It is hard not to compare this to 10-103:NULL KELVIN. You improved in null kelvin in almost every way. The only thing that I prefer in this one is the way the credits roll. Congratulations!


LOVE the atmosphere! The background noises like flickering overhead lights, good stuff~. And those nice, meaty footsteps, MMMM!
Love the light spooky vibe too. Nice for folks like me who can't handle horror well, but still want to experience it to some extent. This is that horror ATMOSPHERE that I dig so much, without me getting jump scared. I like it~.

Excellent work.

About to play your next 10- game too, looking forward to it!

Nice game

amazing game. I loved this, and now Im going to play the second one.(If it is the second on lol.)

Saw this on Alpha Beta Gamer on Youtube and I just had to play. Good work, this is really great!

cool game, want more like this



Great game! Managed to beat without being able to have sound!

I'm loving the whole SCP world, so I gave this a try. It was really good - short but intense :3

If you want to watch it in german, than go for it :3 

Odli膷an koncept i tema, lagano za razumiti i odli膷no za igrati, preporu膷ujem svima da igraju, kratka i jednostavna, zvu膷ni efekti su odli膷ni, sretno u daljnoj gradnji!


Loved the radio implementations

love it

Very atmospheric horror game,i liked idea with police codes,very unique 5\5

A very good game not gonna lie it has so much potential for example you could create more characters to have more histories creatures places facilities idk maybe a class D that has to survive a breach or odk but the game is great keep the good job :D
