I even made a 13th difficulty level just called XIII in another version (also still unpublished). At that point I am honestly not even sure whether it is possible with tool assist.

This guy has been testing with two more difficulties (inconceivable and ludicrous) above insurmountable, prepare to not last more than 5 seconds

Make the next difficulty have SI count on 24, tank having 80k hp like Nightmare mod and immune to fire, Witch is unkillable and will not despawn after aggro

this is the worst thing i have ever seen in this game
perfection

i cant breathe

has anyone beaten this yet? :D

I enjoyed this difficulty. I really love the feeling of incoming death and always black and white gives it a creepy atmosphere.
Even if I like it, I have never beat a single map chapter xd.

Iron Man in expert still the worst because if you're dead, I think you will be back on lobby.

You can play with friends too but they will need the addon too. And you need to host locally.

is insurmountable solo only? can you not play with friends?

Its a mutation.

how to turn on it wont turn on for me

to ez make it harder

Correction: I played that before buffing insurmountable. Its harder now (there are more specials). However it should still be possible to solo. But my goal is to nerf insurmountable just a little bit in the next update.

I planned to rebalance cataclysmic-insurmountable (or rather i already did. i have to playtest it now and then publish the update), because pandemonium is redundant right now. However in the state that is online right now, it is probably even possible to beat some campaigns on insurmountable realism solo. It is just ridiculously difficult. I managed to beat the 1st chapter on dead air and went far enough into the 2nd chapter to show that it can be done. Chapter 4 may require some good bhop or very good melee skills, but i do not think that it is impossible.

Bhop definitely helps in some situations. Aswell as some other speedrun tricks. I did not intend it to be beaten tool assisted, but otherwise cheesing with common boosts or stuff like that is totally fine. It is not supposed to just be about aim or just about quick reactions, but overall skill, experience and knowledge. Good teams should be able to beat fiendish without cheese and too much trouble. However insurmountable is definitely also about problem solving. A big part does not lie within actually shooting stuff but about figuring out how to make it work.Just like lifting a heavy weight turns from a feat of strength to a feat of engineering at some point.

This one is basically just meant for bhop speedrunners, playing this without auto is unbeatable on certain levels

Why? Have you finished insurmountable already?

I want something MUCH harder, just because its gonna be really funny

if someone said this one is " too easy "
that's mean they use Admin system to enable " God_mode 1 " + " Final rescue " for sure. lol

too easy I need more

Well, insurmountable is a synonym for impossible. So i guess it makes sense. xD

A charger*

Yeah nobody beat this. Even with bhopping to mitigate the 1hp speed you are not fast enough to get to key points. 1hp would be fine if you modfied the base speed to 40hp. I do no damage runs all the time when I carry friends on Expert Realism. I find this and even after 42 tries cannot finish the easiest campaign, No Mercy. 9th Diff faces a different problem. A character can take 3 sec of being on fire and one point blank headshot using pump shotgun and it still manages to live.

Insanely fun to play with. It's fun to screw around and see how long I can last. Thanks for making these! How about an eleventh-- nah I'm joking, unless if you happen to have another adjective past "Insurmountable" difficulty.

Congrats Scientist! Want to try pandemonium difficulty sometime?

I did it

I did beat mercy hospital appartment!

I'mma do a challenge starting from easy up to this difficulty. I'll try beat em all on the Big Wat campagin.

A little intense clip I took, It was like something straight out of a movie.

I did not record it

Complete a campaign on this difficulty level.

want to see what

:o Want to see

I did it!

these difficulties youve made are literally for masochists lmao

Blame Valve. If you have a healing item, hold it and they will stop.

Bots will block your movement because they want to heal you.
This can be annoying.

I was close to the saferoom but a Jockey took all of us out lol

Video or demo?

Oops sorry did not notice. But no. Mainly because i do not see a point in doing so. The difficulty here comes from the combination of commons and specials. So just having specials would not gain a big increase in difficulty this way. So in order to get anything out of it, it would require a completely new type of mutation. However if you are really interested in it, there are two options. Either play solo (kill or kick the bots), or make your own mutation. That is not difficulty and feel free to use any parts of this addon. You can open it with gcfscape and look at the content.

could i get an answear to my question

Good luck. You will need it.

thank god

is there any chance of you making last man on earth versions of these difficulities?

Probably. xD But i would first have to come up with a name anyway.

If you come out with another one of these the workshop icon is just gonna be a black square
