Who else would like a new modernized "Trilogy"-like game be A:Isolation 2?
The actual point. A hybridised gameplay "combining" classic shooter FPS and stealth.
The game being now in a planet, but the last chapter. 3 main levels. Two in a planet, and last in space against a "boss" that I describe below.
We would be armed now with pulse rifle or whatever (more weapons later of course), but quickly would we learn (by making every alien the threat they should be, even Cameraliens, as well as finally making justice them justice in terms of height or hugeness, which is ultimately what made the alien scary in the dark once) that a stealth approach might be advised.
Somewhat to enforce the stealth mechanics over shooting, then by doing something like making the first alien unkillable (he would completely regenerate after seconds, head included. Think on the dead space regenerator, regardless the alien originally did that decades before DS came...); by making it a special and unique alien throughout the game, that begins to stalk us in some mid chapter, and becomes final boss eventually, having to eject it into space or something in the last stage in space.
To continue to "enforce" this, warriors would be huge beasts like the first alien, highly resilient to fire, but we would still be able to blow their limbs and making their life harded for them, easier for us, limbs they wouldn't regenerate like the giger-alien pursuing us. Still, they wouldn't detect us since they spawned on screen, and stealthy approaches against them could be possible and even recommended, since we would be saving ammo for other encounters that might truly turn against us because we screwed the stealth.
Runners would know of our position the moment they spawn on screen, and offer It to any other alien/s on screen your. All of them would head toward you when a runner is on screen, and all will attack you instantly. Basically, no stealth approach would be possible as long as there is one of these on screen. Additionally, runners when on their two in dark places should be scary as f**k.., as the one from the third movie was; heck that it was.
Shooting would be of course an alternate way and not desecrated completely. Just less desirable in most situations.
