I would prefer gear being unique like this over the generic damage perk system.
And yeah all predators should have different looking vision modes and sounds/clicks etc. None of the thermals have looked the same in the movies, they’re all pretty unique even down to the audio scanner thing.
I don’t think current thermal even looks good. Its way too clean. Just a blue filter with highlights and no lighting. Lazy as possible, even avp 2010 got it better.
