Wait so will this become a battle royale as the squaddies & friends have to fight both their own summons as well as the demon that tries to kill the man or will they face their own demons first and then the demonic hitman/hitwoman/hitmonkey/hit-other?

Also the demons in question are a bit high level, what do you suggest I set the powerlevel at? Will they shrug off bullets like hail or would the stab of a knife seriously inconvenience them?
