TLDR: first or third person for an open world shooter game against various types of monsters

Hi, i'm planning out a game i would a going to make once i get back to my computer and would like some input on where to place my camera.

My idea is as follows, you are apart of a clean-up squad sent to deal with an anomaly on an island, whilst in the helicopter on the way you are stranded on this island and find it is filled with other anomalies/monster as well as other squads sent there, your objective is to find out what's going on, why this happened and to stop it if you can.

The gameplay would be something of a mix between horizon zero dawn (fighting monsters that aren't necessarily humanoid) and ghost recon wild lands (run and gun), i don't have any more details for now but if you want to ask question i will try and answer

Thanks
