This week, we’re introducing 29 new international flags to Icarus, which are items used to decorate your outposts and bases. Whether you're representing your home or just adding a personal touch to your setup, these flags offer a colorful way to customize your world.
Looking ahead to next week, we’re gearing up to celebrate a major milestone - our 200th weekly patch since Icarus first launched. To mark the occasion, we’ll be introducing a brand-new solar panel, allowing players to better integrate solar setups into their buildings.

This Week: 29 New International Flags
We’ve added 29 new international flags to Icarus, giving players a new way to personalize and decorate their bases. Whether you're flying the flag to represent your home or introducing some colors into your build, these flags are a great way to add character to your outpost.The flags are available at Tier 2 and can be crafted using the Decoration Bench. They require 5 Steel Ingots and 5 Rope each, making them relatively accessible once you've progressed a bit into the tech tree.
Each flag comes with three display variations to suit different base styles and placements. You can choose between a large flagpole for outdoor areas, a smaller standing version for tighter spaces, or a wall-mounted option for a more compact decorative touch. This flexibility allows you to incorporate flags in a way that fits your aesthetic, whether you're building a rugged survival shelter or a high-tech base.
Whether you're celebrating your roots or just want to bring some extra color to your build, these new flag decorations offer a fun and meaningful way to express yourself in-game.

Next Week: Flat Solar Panels
Next week, we’re introducing a new style of solar panel that offers the same power-generating functionality as the existing model but with a fresh look. This new design gives players more visual variety when building and customizing their power setups, allowing for a solar option that better fits different base styles. Functionally, it operates just like the current solar panel, providing clean, renewable energy during the day. Check out the preview below.
