In 2016, Paradox Development Studio released Stellaris, a grand strategy title set in space. Now, three years later, the title is celebrating its various changes, updates, and downloadable content with a free weekend on PC. You can download and play Stellaris on Steam for free right now, until May 12th, 1 PM PDT.

If that weren’t enough, the base game along with its DLC are currently discounted. You can get Stellaris for a whopping 75 percent off with DLC seeing discounts ranging from 50 percent off (Utopia, Apocalypse) and 20 percent off (MegaCorp). As with any Paradox Interactive title, there’s lots of additional DLC, but if you really like Stellaris, it’s advisable to pick up the Utopia DLC above all. Stellaris is also available for Xbox One and PS4.

Paradox Development Studio has been busy supporting Stellaris with updates, but also recently released Imperator: Rome. The grand strategy title sees players managing their nation during the establishment of the Roman Empire. You can read more about it in GamingBolt’s official review here.

The newest and coolest looking expansion for Paradox’s Stellaris is now live with Megacorp. Currently available for PC, it introduces a huge range of trading, and features to ensure you’re top of the corporate food chain. Check out the launch trailer below for some of the things that Megacorp will allow.

Essentially, players will take over a large corporate empire as its CEO and must expand their business through any means necessary. If that means buying and selling pops in the Galactic Slave Market or building enormous Megastructures like Mega-Art Installations and Matter Decompressors, so be it. Megacorp even lets you go crazy with your population expansion, creating an enormous megacity that covers several planets.

Other features include new civics, Caravaneer Fleets that carry interesting bargains, Ascension perks, three additional Advisors, and much more. Megacorp costs $19.99 standalone, but if you’re interesting in Stellaris as a whole, the game and its DLC are currently on sale. Head on over to Steam to avail up to 60 percent off on different editions.
