Paradox have launched an update for their space strategy Stellaris free of charge. It has more or less revamped the game as we know it, but the optional Apocalypse paid DLC is the one that adds new content.
Stellaris has received both the 2.0 update dubbed ''Cherryh'' and the Apocalypse DLC in quick succession, bringing players a lot of needed fixes and quality of life improvements for the game.
It has been suffering from the same issue for a while now where you basically had just one way of getting things done - mass your forces up into one big blob of ships and send them to wreak havoc. Betting everything on defence didn't seem to be profitable and these two lingering issues have finally been addressed.

Adding Apocalypse on top of that made for more balance challenges as the DLC introduces two new ship classes: The Titan and The Colossus. The second one destroys planets.
The Titan, while unable to destroy planets and not as big as The Colossus, is still a pretty massive vessel that serves as the flagship of your fleet.
Just adding two massive ships that would wipe the floor with enemy factions wouldn't be a good idea for a strategy game, unless they had some way of countering them. Enter Ion Cannons - space station based defensive instalations with this exact purpose in mind.

The issue of doomstacks which were a cookie cutter strategy in Stellaris since launch, seems to be resolved now, but only time combined with player tenacity can tell. There is now a cap on how many ships can be in a single fleet, so if you were planing on putting those Titans in a doomstack of your own, you may want to rethink what such ideas imply about your character.
