Stellaris, Paradox's 4X turn-based strategy game, is by all accounts pretty damn good, but even so it does suffer from some issues. Most notably, the mid-game is kind of boring once you've played it for a while as there really isn't much to do until some of the later stages. If this is something that bothers you as well, worry not as the Leviathans Story DLC has just arrived to address those specific complaints!
With Leviathans you will be able to not only encounter powerful space entities with "mysterious origins and motives", but also visit brand new trading outposts in order to better your knowledge of the universe and to engage in good ol' trade. Most interestingly, you'll also be able to partake in an end-game scenario called "War in Heaven" when two ancient Fallen Empires decide to renew old grievances and engage in an all-out war! However, if it was the Leviathans themselves that have caught your eye the most, here's a rather spooky little teaser trailer foreshadowing their arrival:
As for the free Heinlein update, to call it massive would be a rather... massive understatement. You can read about all of the changes over at the Paradox Forums, but do be warned, you're going to be there for quite a while! But if you're just interested in the short version, here are all of the features Paradox decided to spotlight as the major parts of the update:
• A convenient Auto-Explore feature.
• Rally points for your freshly-assembled Navy.
• The Expansion Planner Interface.
• An overhaul of Strategic Resources.
• Clearer specialization/role for ship types.
• More options for customizing new galaxies.
• New smarter Sector Governors.
And finally, its well worth mentioning that the reviews for Leviathans have so far been outstanding. So if you're interested in squeezing even more playtime out of Stellaris, it might just be worth giving it a look.
