Codes, Factory Simulator Wiki

Promo Codes are a feature added to redeem rewards. Redeeming promo codes gives players prizes such as money and crates. Most, if not, all promo codes are available for a limited time and eventually expire. To redeem codes, players can go to the side of their base or to the Shop section and type in Promo Code box. Codes can be found on the develop group's Twitter (@teamgamingglove). All codes that reward the player in-game currency scale the rewards with the player's factory tier.
