Amplitude Studios is celebrating its fifth birthday with its second annual Endless Day: a day that lasts from 21 to 25 January, and that offers up rare heroes and achievements to people who play their games during this time, and who fulfil various conditions. That stuff is detailed here, and includes a trio of heroes simply for starting new games of Endless Space, Endless Legend, and Dungeon of the Endless. You can also bag some time-limited achievements, though these will require a mite more effort.
(Amplitude hints here that you might be able to get these things after January 25, perhaps by mucking about with the time settings on your computer.)
During a celebratory livestream, Amplitude also announced a new expansion for Endless Legend titled Shifters. Ampz sez "this expansion will include a new Major Faction called The Allayi. This new civilization will be able to ‘shift’ during long winters", a fine alternative to sticking the heating on and hugging a hot water bottle, I reckon. Meanwhile, "all factions will also be able to collect a new resource called the ‘Pearls of Auriga’, enabling them to unlock new powers through the ‘Altar of Auriga’ and modify the upcoming winters’ impact". Good on them.
Here's a picture of them there Shifters (ta, RPS):
One of the upcoming Endless Space 2's new factions has been revealed as well. The Sophons are one of ES2's eight major factions, and they're basically insectoid scientists.
