1. You unlock machines through the campaign missions.
2. When you go into a mission it takes everything exept the drill as it is essential, it's due to the fact that bringing materials and other items into a new mission would make it too easy.
3. In each mission you're given a weapon to defend yourself which can be found in a crate in the start point.
4. The game may not hold your hand through you'r endeavours but there are explanations for the function of the buildings in the start area of the campaign.
5. You drag items out of the inventory and put the on the ground, the rack will automatically will pick up 3 stacks of a specific item.

While some things do lack explanation if you pay close attention to what is in front of you (or just go to the wiki) there is plenty of information to gather which will explain everything in detail.

If you have more questions feel free to submit them here and I will anwser them whenever I'm available, or just go to the wiki if you don't want to wait hours or even days.

Honestly simple reading should give you all you need to know to complete each mission. It's very specific on what you need to do if you read the mission objective before starting each mission. Each mission completion will reward you with Permanent Lumens that you can use to permanently unlock upgrades in the Campaign Hub. Personally I prioritized upgrading my drill so that it's permanently unlocked during the campaign missions. Makes drilling so much faster and easier. Second priority is using your permanent Lumens on your favorite weapon. Then use them on your favorite character upgrades or tech. Drill and weapons is the most important though.

I too found the quick tutorial hard at first and a bit confusing. The campaign is really the proper tutorial introducing each element of the game bit by bit. Once you have finished it you are ready for some proper randoms. In campaign like the random maps upgrading your drills early is quite important and worth concentrating on.

Unlocking the research swap every 5 minutes asap at the base lab should be top priority. This will let the options cycle so you can pick and choose the best buffs.

It's fun although most of the weapons are lacklustre, having to click for every bullet is a chore so I opted for the machine gun.

Even if you fail a mission you get half the lumen reward so it can be worth tanking a few of them straight away to save time on upgrades. Though as above permanently unlocking your drill upgrades will save you tons of headaches early on but I opted for the backpack over weapons as the majority of levels are pretty tame to start so you have plenty of time to build your weapon workshop and upgrade it inside each mission.

Focus on permanent upgrades to your resource gathering, as things like weapon buffs, turrets upgrades and crafting are manageable within the missions. Also, don't save anything for the final drill upgrade because you don't get lumen farms until the final mission sadly.

I loved the tutorial (demo), it was intriguing, so I bought the game....
I've tried the Campaign, and I dont get it - there's lots of machines, mostly locked, nothing to upgrade the drill. I went down a lift into different levels but it seems to take everything I get off me? I also can't buy a pistol since I can't upgrade my drill to be able to get the resources required. The campaign mode needs to be explained... I cant find anything explaining how it works...
So I tried one of the more 'sandbox' type of modes - where I just have a reactor and need to build. I liked it at first, until my inventory got full and I had to try and work out how to interact with racks, nothing, looked at key-bindings, 'space' to interact, tried it... nothing.

This could be a great game but it needs a lot of work on the tutorial and explaining modes, it's really frustrating trying to work it out as a player, especially when you have a timer ticking down to an attacking wave,

Skill issue. After having played the demo myself, everything is explained properly. You are told what to do and are pointed where to go. The gradually unlocking nature of the main base is pretty self evident as well.

I agree, why is the tutorial so much more fun than the campaign ?!
Can't do anything in the campaign. So laborious in boring levels to bring back a handful of lumen and not upgrade much.

Don't like that things are just locked and we can't build ourselves. Seems would be more fun to bring back the metal we have in inventory at the end of the level (like the lumen) and just build our base ourselves and upgrade what we want. I'm only like 3 levels in but I don't get how I'm even gonna get metal? I'm gonna have to wait to upgrade some driller machine?
That's boring. I,m gonna stop there.

Tutorial was so fun, mine and build and fight and upgrade. The levels/accent on ''roguelike'' element (permanent upgrades carried through levels) isn't the way to go imo.

Phew ..thank gad, I was worried for a sec. It's stunning how ppl can't be bothered to explore the UI, settings, menu, descriptions, et al.

It sounds like you might enjoy random maps even more. I didn't even bother with the campaign and just jumped into a random map. You can immediately start collecting resources, upgrading/researching all abilities and base buildings, and just face wave after wave. I much prefer just jumping into the map and playing that way. Seems the proper way that the game was meant to be played anyways. A proper rogue-like, base-building mining game.
