Hello, First I'll start by saying my grammar is not the best so sorry if that bothers people! But my idea I thought of that would be cool is if you could get the rights to Freddy and add him as a bonus character. And like how Jason has music, for Freddy, it'd just be creepy children/girls singing his theme with no background music at all and gets louder as he gets near the counselors. One ability could be taunt and what it does is basically raises the fear levels of any nearby counselors making the sense ability more useful for Freddy. And how you kill him...well of course use fire! maybe instead of using the gas on the boat or car the counselors can choose to use it on Freddy coating him in it and finding a way to light him on fire but maybe if he goes into the water it washes it off so you HAVE to do it only when the times right and everyone is ready or you waste the gas for that match.
Another idea I had was if you could make that happen, a Freddy vs Jason mode type deal where each killer fights the other to kill more counselors than the other. Maybe increase the number of counselors in this game mode to try and balance it a little better.
I know what I suggest would be a ton of work making another killer and trying to make him different than Jason but I really think this would help boost sales and keep people playing longer and as we know companies like money ^-~ Could make it free content or DLC really. I'd love to hear what others would have to say and any suggestions on what his abilities would be or how to kill him, as I'm sure others can improve upon my idea!
