I haven’t had any problems, except for fighting that Goliath alien. I managed to take one down solo, but only by jumping across a chasm and then taking pot shots at him while he stared at me from the other side. I could not get clean shots off at him while running away. I actually killed him by throwing a grenade behind him, and when he turned around to shield from the blast, I shot him in his soft unprotected backside until he collapsed.

I personally have yet to die in the game, but two of my friends who joined me just ran off without any introduction to the game and proceeded to get themselves killed over and over again. So if you pay attention to the training at the beginning, it shouldn’t be too difficult.

The farther you wander from your starting area, the more difficult the aliens get. So stay closer to home until you’ve leveled up your weapons and base defenses and you’ll be fine, even solo. Of the 7 bases I currently have set up, only one has been attacked by aliens so far, and they were easy to clean up by myself.

As far as factory automation, it can sometimes be a chore as a single player, but it’s not too hard. As long as you have the patience to plot out resource production lines, it’s not too bad. The hardest thing right now is that there’s no transportation between bases besides walking there yourself, so it can be time-consuming going back and forth to check on various bases. Especially since most of the resource nodes are scattered. And you can’t just build anywhere like Satisfactory, so you need to drop Base Cores here and there so you can run rails between bases for resources.

I still don’t know how large the game’s map is, but what I’ve uncovered so far is massive. It takes me maybe 10 minutes to walk across my currently-explored area, and there’s still a lot of black undiscovered areas on my map in all directions!
