Amplitude Studios’ Endless universe has been built up quite extensively over the years. Whether it’s the 4X machinations of Endless Space or the rogue-lite quirks of Dungeon of the Endless, there’s quite a lot to go through. The entire franchise is on sale this weekend, but you can also try any of the games for free until January 28th, 7 AM PT.

The games in question include Endless Legend, a 4X title with stunning art-work and compelling factions. Then there’s Endless Space 2, a 4X space expansion title that builds significantly on the first game. Finally, we have Dungeon of the Endless, which mixes way too many genres to count (more about that here).

If any of these titles catch your fancy, then you can pick them up for pretty deep discounts on Steam (and even snag the Endless Space Collection for cheap). Amplitude continues to release new expansions for Endless Space 2 and Endless Legend. The former has received Penumbra, which brings the hack-tastic Umbral Choir to the universe, while the latter receives Symbiosis with its assimilating Mykara.
