Bulwark Studios and Kasedo Games have officially released Warhammer 40,000: Mechanicus for Linux after having a 'soft launch' in December last year.
Announced earlier, the 1.1.3 update promotes the Linux and Mac versions to a fully supported status—awesome! In addition, they've updated the Unity game engine version used to 2017.4.19f1 and a healthy dose of bugs have been fixed too. For specifics, you can see here.
As for what's coming next for Mechanicus, they said they're going to be adding in at least a custom difficulty challenge, more troops, more environments and so on. They have more plans, but they're not going into detail about them just yet.
I've had a really great time with it and plan to play plenty more. They get a lot of things just right like the atmosphere, the unit design, the environment art and so on it's wonderful to play through. The mix of decision making as you explore, with the XCOM-like combat that still has it's own slightly unique take on it has made it quite captivating and it certainly sucked my interested in.
