New Gamemode (Like a boss fight)

Question/suggestion about new game mode that could be funny and change the gameplay a bit.

Feel free to discuss in comments what could be added/changed etc.

If anyone played TF2 with Saxton Hale gamemode, You already know what I have in mind.

There is a person on YT (JayDaddy) that had a compilation of Horror movie killers that he gets rid of.

So here is my idea (probably there was something like that already)

How about a gamemode that switches roles, as survivor (or some big entity spawn) a 'Final Boss' (1 player) you have a lot of HitPoints and 4 killers try to kill you (free themselves from entity/the realm) , with M1 and powers that would obviously be nerfed a bit.

(Boss HP could be shown like the end game timer)

And you can use some of their powers back at them, lets say, trapper would slow down the Boss with his traps if he gets in one, but Boss can also pick up 1 of his traps and put it down to trap killers if they walk into it. Or redirect Nemesis zombies, hack Skullmerchants drones to work for him etc.

So killers would have to be careful with using powers, but also would have to use it to debuff the boss in some ways.

As a boss you could have some abilities like charging a dash, small regeneration but staying in place, shield etc. chosen in lobby

You would have to 'grab' (M1) the killers and put them back into entities claws or cages somewhere on the map or something to 'tame' them back. They could have like 5 'hook stages' and no need for rescue, they would just break free after a few seconds (like 30 or something).

Basically

Bosses objective - cage 4 killers 5 times each

Killers objective - kill the Boss

Simple idea, not very well thought out, just came into my mind.

(Please don't be too harsh)
