What a coinkydink, I wrote up another update about nine days ago. I have no clue how long my access to the alpha is going to remain and I haven't played again since that update.
For more shenanigans of the video variety,
Draegast just uploaded some gameplay two hours ago as of this writing. Hilariously, he answers my hypothetical "if you're incompetent" question from the previous post.
Combat and adversity. That's what most of the games I play feature, and this one is no exception.
I haven't gotten close enough to really examine the enemies so I can't tell if there's only one type or if the two guys in this image are subtly different. In any case, you're both equipped with two-shot shotguns and should shoot each other on sight. Not pictured, there are two parking spots around the first volcanic area. I couldn't stop at the first one I chose because there was an enemy drillship there. It periodically drills beneath the surface only to pop up later and release all of the enemies within it. They're difficult to assault, having at least one turret module installed. Discord chatter led me to believe that you could take one over if you installed your faction's core in it.
After killing enemies, you can do what your gamer instincts tell you to and loot the bodies. You can get loads of crap this way. Back when I made my first post, you seemed to only get the simplest building components. An update must have happened as I looted new ammo types, structures that you can place in your drillship, and higher-tier components as well.
Turrets. Something that, at this point, aren't really explained. I have since lost the relevant picture, but before I realized turrets were a thing, enemies destroyed every single module on my drillship. You'll have to settle for the above "damaged wall" image instead. You can tell visually how damaged a thing is. Not destroyed? Looks like that. Completely destroyed? I refer you to the "damaged shitbox" section of my first update - holes in the walls big enough to walk through.
You can recover from just about anything. Enemies destroyed all of your modules? Pop around the map, mine a shitload of resources, and head back to map location 1. Your sub is still there, its crafting machinery available to craft replacements. But the only fix for death is loading from your last save.
I'll leave you with this. I have no clue what it is. I'm assuming it's a massive improvement on the objective system. During my last update, the objective was "run up to the enemy drill thingy, press 'E', and it disappears." This looks like something that'll actually be interesting to mess with.
Closing remarks:
It's likely too late for you to get in on the closed alpha. Given the improvements I saw over just the past week, I'd seriously consider a purchase. Maybe when multiplayer is a thing.
