This time last week, we learned of Endless Space 2 and Endless Legend's new Supremacy and Inferno expansions—both of which land today. This time this week, I'm here to tell you both games are getting a free weekend. 

From now through Sunday at 10am PST / 6pm BST, Endless Space 2 and Endless Legend are free to try (as are Amplitude's other games Dungeon of the Endless and the original Endless Space). More on that features in the trailer above. If you already own all of the developer's games, the free weekend's custom-made website and stretch goals might be of interest. 

Here's Amplitude with the skinny: 

On our free weekend website, we’ll be putting up Stretch Goals that will be unlocked based on the total number of hours played by our community, across all of our games. 

Last year, 240,000 participated in the free weekend, unlocking all six reward tiers in the process. This year, we're back with another Community Challenge!

Simply play Endless Legend, Dungeon of the Endless, or Endless Space 2 and reach 1 million hours of collective playtime to help the community unlock all the rewards, which include a Cravers Prime skin that was only available during Early Access, and as stretch goals, 6 additional fleet skins to unlock. 

Said free weekend website lives this way. 

If you fancy Endless Legend's new Inferno expansion, and Endless Space 2's new Supremacy add-on, here's some fresh in-game footage. First, Inferno: 

And second, Supremacy:

Both expansions are available on Steam, and cost £9.89/$11.69 (ten percent off till August 30) each; or £17.58/$ 20.78 (20 percent off) when purchased together.  

You wait all day for a Fire Ship and/or Dreadnought then two come along at once. Amplitude Studios has unveiled new "major" expansions for both Endless Space 2 and Endless Legend. Both are due on August 2. 

Which is one week from today. Lovely. Let's have some trailers, then we'll talk to the nuts and bolts. First, Endless Legend Inferno.

Second, Endless Space 2 Supremacy.

Working alongside NGD Studios—the folk responsible for the Master of Orion reboot—Amplitude has added the Kapaki, a Lava Biome and Dust Eclipses to Endless Legend via Inferno. Forced to leave their native volcanic homeland, the former are determined to set up shop among the ash, fire and ruin and are billed as a "crafty new faction of tinkers and inventors."

The fiery landscape isn't exactly brimming with life, but is ripe in industry, science, dust and volcanic anomalies—which is where Dust Eclipses come in. 

"In these new events, you’ll notice the skies darken and the atmosphere become thick with Dust," explains publisher Sega. "Now, in normal conditions, this would be a pain, but Auriga is special, and these Dust infusions will create short-lived 'Dust Confluxes' all over the map, bestowing a temporary boon to whichever army reaches them first."

Onto Endless Space 2, and The Hissho mark Supremacy's newest major faction. Having first featured in the original ES, the group's central feature is Keii, "or honor", that powers special abilities and can boost systems and fleets mid-battle. Keii is replenished through combat, which leads Sega to say: "space is about get a little bit rowdier." The Hissho also bring minor faction Illo to fight—machines said to be "hell-bent" on eliminating the weakest species of war.  

Supremacy also brings with it a new ship type for all factions. Here's more on The Behemoths: 

Ever wished for a gigantic ship that was customizable to your specific purposes? Wish no more! These gigantic ships are remnants of the mysterious Endless era, providing significant economic or scientific boosts, and can be customized into “Obliterator”, “Juggernaut”, and “Citadel” specializations. The Hissho start the game with one they’ve just awoken, and the rest of the players can catch up through a cooperative quest. 

Again, both Endless Space 2 Supremacy and Endless Legend Inferno land on August 2. Available on Steam, pre-orders cost £9.89/$11.69 (ten percent off) each, or £17.58/$ 20.78 (20 percent) when purchased together.
