as the plot is placed in present, ii can imagine my prefect ending.
aliens are wiped out, but, unfortunately, one remains and, nobody knows how, ends up in adi habitat! It first takes out alec and tom, then kills everyone in the building, only one anonymous hero, who used to work there as a janitor, stays alive. He picks up the weapon and shoots the xenomorph! But acid blood falls on all the computers, sketches and sculptures and everything related to adi alien/predator designs, destroying them forever.
and then building collapse.
that would be awesome.
