Hellraiser:confrontation

well I guess since campaigns aren't my thing I'm going to try for the minigame genre. Hellraiser:Confrontation isn't original I guess since it's hellraiser,but I haven't seen many games based off horror films. Anyways, the game starts off as you picking from a number of characters. I didn't exactly want the whole game to be just you running from pinhead but actually having power to fight some of his minions, while also trying to put him back into the cube.
Characters:
Cop-Yes yes,your average law upholder and worker in the police force. Being that you're fighting demons his gun doesn't hurt them much...but it can be upgraded and will be much more efficient.

Teenage girl-Every horror film always has some girl screaming her head off,humourously this one has an ability that is a shreak that will stun the opponents for a slight moment of time.

Priest-Pretty much the healer, he can use some light spells to drive back foes and later on revive party members. Most likely needed for survival

Druggie-Dude hooked on drugs,depending on what it takes he can make himself run faster, feign death(knock himself out)and other abilites. But he can suffer from an overdose,or end up killing himself.

Physic-Little kid with telekinetic powers,he can help get past obstacles that would be humanly impossible for someone else to accomplish. Levers, unreachable buttons,etc etc. Powerful spells but low health, not the exact person you'd want to tank a demon

Matyr-A mysterious man that always carries a Bible with him. He is somewhat like the priest,but he is more holy spells then healing. Once leveled high enough he can tear a demon apart with his mind(spell)

I have 2-3 more characters still in development but I've also wanted to add secret characters,which would consist of characters from other horror flims just for fun:Freddy kruger,jason,leatherface..just to keep it interesting

The game will be about 5 players,and it's sort of a mixture of survival and rpg. As all hellraisers(or from the movies i've seen)you must retrieve the cube,and seal pinhead back in it...or be stuck in hellworld. Any help would be appreciated,if you can do skins and models then your help would be GREATLY appreciated. Anyone interested?Just I know about horror more than I do campaigns so I'm giving this a shot

So does one player control the Minions or are they computer controlled? I'd also like to know more about the gameplay, players need to find the cube yes, but from where and how? What kinds of obstacles are there, is the cubes location randomised and so on.

The minion will be computer controlled. Players will have to defeat bosses(pretty much some of pinhead's lackeys you see in the movie)to get a key..each key will open a door in hellworld,each door can only be opened by a key except for one,it has a powerful seal on it to keep pinhead and the players locked from it's prize....the cube. To destroy the seal you must retrieve a rune from a necromancer,only if you can defeat pinhead in battle first. The field of battle would be under the necromancer's power,that way pinhead isn't stronger then you,but making the fight fair. Win and you get the rune, you must use that rune to open the door. The game won't end when you get the cube...you'll have one more battle with pinhead,this time he's at full power...this will be the part that's somewhat doom 3ish. The only way you'll beat pinhead is if you can use the cube on him 3 times,sounds easy but you'll have to survive his attacks and minions he could summon. Parts of this could change as development goes but pretty much this is the foundation I have the game on

My alternate decision would be that the players would have to rebuild the cube,getting a piece from the bosses.
