This mod adds replicators, machines which can produce items using nothing but electricity. Lower tiers of replicators are the most energy efficient and can essentially transform depleted, empty land into a resource. Higher tier replicators can simplify production lines or otherwise act as a convenience. Tier 1 replicators can replace depleted mining drills, allowing your expansion to be for growth rather than necessity.
You aren't alone. Someone, something out there wants you to succeed. You've been noticing strange crates that don't look like they're from this planet landing nearby occasionally. They seem to contain supplies for you. You don't know what or who's sending them, but they're certainly helpful.
