Latest, Doom: The Dark Age. It really makes me want to do a revisit of Doom 2016, but ain't nobody got time for that.
I was trying to get Aliens: Dark Descent wrapped up before Doom released, but didn't quite make it. So that's still sitting unfinished...
It's cool, but hard. Some neat mechanisms I haven't run across in this style of game before, like controlling the squad as a single unit.
All my decent soldiers are injured, so I've been trying to complete a mission with all rookies. And it's not going well.
