14 DAY TRIAL // The Last Federation, a turn-based strategy game with 4X elements developed and published by Arcen Games LLC, is available on Steam for Linux with an 80% discount.
The Linux platform does have quite a few strategies; any new title will have to be good. The Last Federation has been proposed by the community and had a great media reception, so you know it's a good investment. It's also worth pointing out that the promotions will only last for a few more hours.
"From the creators of AI War: Fleet Command comes an all-new grand strategy title with turn-based tactical combat, set in a deep simulation of an entire solar system and its billions of inhabitants. You are the last of a murdered race, determined to unify or destroy the 8 others," is noted on Steam.
Just like any other 4X game, The Last Federation will provide priceless replayability, not to mention the fact that the game also comes with a DLC called Betrayed Hope, which further expands the gameplay.
The Last Federation has really low systems requirements. Users will need at least Ubuntu 10.10 (most likely any Linux distro will work), a 2.2Ghz CPU, 2 GB of RAM, and 1GB of HDD space. The promotion is set to expire in just a few hours so you won't have a lot of time. Enjoy!
