How to Redeem Once Human Codes?
Time needed: 4 minutes
Follow these steps to redeem your Once Human Codes:
- Complete the Tutorial: You usually need to complete the initial tutorial questline (often called “Eve of Evolution”) and enter the main open world before the redemption option becomes available.
- Open the Menu: Press the Escape (Esc) key to open the main menu, or sometimes the dedicated F3 key.
- Navigate to Events: Look for and select “Shop Event” and then choose the “Events” option.
- Find the Redeem Code Button: Look for a “Redeem Code” button, often located in the bottom right-hand corner of the screen, or sometimes you can just press X.
- Enter the Code: A box will appear where you can type or paste your code.
- Redeem: Select Confirm or Redeem to claim your rewards.
Alternative Method (Sometimes Used, or for Mobile):
Some updates have moved the redemption option to a different location:
- Open the Settings: Go to the Settings menu (often accessed via the top right-hand corner).
- Find Redeem Code: Look for the “Redeem Code” option, which may be under an “Account” tab or located at the bottom of the settings menu.
- Enter the Code: Enter the code and confirm.
- Note: The rewards are usually added directly to your account immediately after redemption, as they typically do not go to the in-game mailbox. Ensure you enter the codes exactly as they are written (case-sensitive).
Top 5 Gameplay Strategy Tips for Once Human
- Prioritize Activating Teleportation Towers Unlock nearby Communication Towers as early as possible because they function as essential fast-travel points. This simple action significantly reduces travel time across the large open world, saving immense effort and resources.
- Master the Crafting & Resource Loop You should build a furnace and disassembly bench immediately to start creating charcoal and refining scrap materials into ingots and other necessities. Since dropped gear cannot be repaired, prioritize finding and crafting your own blueprints for durable, long-term equipment.
- Get Your Territory Deviants Working Capture and place Territory Deviants, like the Digby Boy (ore) and Logging Beaver (wood), into Isolated Securement Units as soon as possible. These companions automatically farm essential logs and ores while you are out adventuring, providing a crucial passive income of materials.
- Focus on Weekly Starchrom Rewards Regularly purify your Eclipse Cortexes at the Stardust Resonant Filter in your base to earn Starchrom, the vital currency for high-tier blueprints. Remember that this process will attract strong waves of Deviations, so you must build up your base defenses, including walls and turrets, before starting the purification.
- Engage with the Community for Progression Do not hesitate to join a Hive (guild) and ask other players for help with difficult content like Monoliths or high-level resource farming. Cooperation makes tough challenges much easier, and other players often share valuable equipment and knowledge with newcomers.
More About Once Human
Once Human is a free-to-play, post-apocalyptic title that mashes up five distinct video game genres: survival, crafting, MMO, open-world, and third-person shooter. You explore a world corrupted by an alien substance called Stardust, which mutated creatures and objects into grotesque Deviations. As a Meta-Human, players must master building a sanctuary and fighting bizarre cosmic horrors to survive.
Consequently, this unique blend of mechanics provides a great deal of content for both solo and cooperative play. Furthermore, players collect and customize numerous weapons while also taming strange Deviant companions to help them in combat and resource gathering. Ultimately, they try to uncover the truth behind the Starfall and determine the future of a broken world.
