Stellaris: Apocalypse

Stellaris: Apocalypse is a full expansion which redefines stellar warfare for all players with a host of new offensive and defensive options. Destroy entire worlds with terrifying new planet-killer weapons, fight against (or alongside) ruthless space pirates, and maybe discover a few non-violent game features as well.

The Apocalypse expansion includes:

THAT'S NO MOON, NEITHER IS THAT ONE, THAT ONE MIGHT BE A MOON, WAIT, NO
Keep the local systems in line with fear of the new “Colossus” planet-killer weapon – a technological terror that eliminates entire worlds from the universe
