About Unknown Planet

Unknown Planet is an open world adventure survival game, set on an alien planet with randomly generated worlds.

Explore

After your spacecraft has crash landed, you wake up on a mysterious planet equipped with nothing. You'll need to collect raw materials, build primitive tools, eat, drink, and start on your exploration journey to uncover areas ranging from friendly grass fields to crimson forests, lava wastelands and bio-luminescent biomes full of lifeforms that want to eat you.

Build

Build your base, grow farms to sustain yourself, craft a light for nighttime, smelt metals, replenish your supplies, craft biofuel and batteries to power your buildings, develop the necessary tools and equipment, store your resources and advance through the tech tree by defeating bosses.

Survive

Defend yourself from the fauna by crafting more advanced armor, melee weapons, ranged weapons and ammo. Manage your hunger and thirst by scavenging for food and water, cooking recipes, planting seeds and growing vegetable gardens. Find and explore different biomes to find rarer resources to help you craft more advanced items and survive until you can rebuild your spacecraft and find a way to make it off the planet alive.

Such a cute game. No story at all which is a slight disappointment but I liked everything else. The fluid motions, the bright colors, the simplicity, and the soundtrack. Such great music while playing this game that I didn't even put on a youtube video for background sound. It only took me a few hours to beat but that's fine. I enjoyed those few hours. I'd love to see them add more to the game, perhaps another planet you crash land on after you get off of the first one.

MUCK but in an alien world. Actually, really well-made game though. Simple, and so optimized that it boots up in seconds, saves in ms and loads in seconds. Big Fan!

9.8/10 Will keep playing. Very nice little game. And very addicting. Keys take a moment to get used to but nothing game breaking. Just new. Fun game to spend time with. Not super easy either since you need to pay attention every now and again on enemies and where to get things. Just pay attention to biomes, text info and search the areas thoroughly to find different things.

This game is pretty good. It does need two things to make it an even better game. 1. More content 2. Better graphics Though I am having trouble getting cellulose, I don't know how to get it.

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.
