Getting Started in Lethal Company

Suits and ship decorations are purely cosmetic — they don't affect gameplay, so buy them for style, not stats.
Scan creatures you encounter to fill out your bestiary — useful both for tracking progress and for learning what you're dealing with.

The 8 purchasable tools from the Terminal store are worth prioritizing early, since they directly help with scavenging and survival rather than just cosmetics.
