So I installed "Mechanicus" from steam and played the tutorial mission this morning.
Its pretty interesting.
The Plot: You are the leader of a Mechanicus ship sent to a planet where another mechanicus team went missing. You and you're delightful crew explore and find Necrons. Now its a race against time to salvage as much tech and information as possible before all the Necrons wake up. Honestly the crew is pretty cool so far. You have the religious fundie that recites scripture and he hates heretical technology, you have the curious analyst that wants to study everything even if she shouldn't, The commander of the troops that cares for her skittari soldiers, and a few other colorful character that supports your protagonist.
The game mechanics: Its very interesting. You view everything from your ship through a star wars style 3D holomap of a dungeon. If you've ever played "Darkest Dungeon" its very similar. You put together a team of troops (cannon fodder) and tech priests (they do everything else) and you go room to room just like Darkest Dungeons. Some rooms have enemies, some have treasures, some have decisions you have to make, and some are just empty. You explore the ruins/tombs and fight necrons. Combat is a lot like the original Fallout games from the 90s. Every soldier rolls initiative and fights in turn. You move the unit around the map, click on the weapon you want to use and select the target. At the end of the turn everyone re-rolls initiative and the new turn starts. You can also collect and use command points during combat which allows you to do an extra action, fire a special gun, or move further. You collect command points by defeating enemies, loosing troops, or from collecting data on the battlefield. Its not really like XCOM at all (no cover mechanic that I can see). Tech priests (and maybe troops?) also are customizable and level up from experience and can be kitted out as you like from collecting in game currency.
I've only played the tutorial so far but its very intriguing. I am kind of surprised they went with the old Fallout 90s style combat as opposed to say the fast paces xcom combat style. Honestly its more strategic RPG (Like Fallout or Darkest Dungeons) than tactical squad game (as far as I can tell). I like it.
