Scrap Collector is a game where you stack cards to craft new items, make new buildings, and fight the enemies of the overgrown earth. An example is if you have a "Bot" card and place it on to a "Junk Pile" card will spawn material cards to make new cards.

Explore
You can sell cards to purchase "Explore" cards. "Explore" cards allow you to search an area for resources, enemies, or even random encounters!! Each area has a specific theme as well as new enemies, resources, events, and bosses.

Power
Some cards will require a power source to be allowed to them at the end of each in-game day to be functional. A constant supply of power is crucial to progression

Knowledge
You unlock new buildings, bots, and blueprints by spending "Ancient Knowledge" cards to purchase them.

Automation
As you progress you can begin to automate nearly every task. An explain is the "Assembler" card. If you slot a blueprint into the "Assembler" the card will pull all required materials to make the blueprint and craft it without the player having to do anything.
