My honest opinion is that I would never play a game that tried that. It’s too much genre diversity in one game.

I think extraction is oversaturated at the moment/too heavily competed. As do I think the 5v5 team based shooters are.

I also think that at the point of adding survival ontop of it, you are trying to advertise to too broad of an audience. Your survival open world mode would be significantly different mechanics wise than your extraction mode, so you would essentially need to make an entire different game just for that mode. They are two polar opposite game styles. Extraction style is a fast paced perma death style mode with no real intent outside collection to increase char strength and skills, where survival is slow paced by norm and would need some form of driving factor to keep people interested in playing the mode, as the primary reason to play it (get shit and get out) is no longer in play.

if its a passion project/not expecting any return out of it. I would say go for it but, I think that if you intended to make it a monetization thing and have it take off, its a bit ambitious and I think you should start with one or the other.
