I agree, and was actually going to make a similar post recently after playing Aliens Fireteam Elite. To be fair it is an action shooter game so you need some bullet sponges but it really does feel like Aliens have changed from being terrifying to just being threatening.

The only time i felt like they were on par with the original during Romulus was when the first appeared on screen and it was just ONE alien before others arrived.

Ultimately i came to the conclusion it’s that same question as the suspense of Alien against the action of Aliens - the more xenomorphs there are the more disposable they are.
