Ashwend

Ashwend is a first-person multiplayer survival game. You start with nothing on a remote planet. Gather, craft and build to stay alive, then fight, raid or team up with the people around you. Every world lasts thirty days. Then the server wipes and everyone starts again on a new one.
A whole planet
There is no map edge. The world is a small planet with continents, seas you can swim, burnt-out villages and the roads between them. The sun, moon and stars move as they would where you stand, a day lasts thirty minutes, and the weather follows real-world forecasts.

Start with nothing
You arrive with empty hands. Pick up stones and branches, make stone tools, and work your way up to iron by smelting ore in a furnace. A workbench unlocks most recipes, and upgrading it unlocks the best gear. The rarest parts can't be crafted: you find them in the salvage of burnt-out houses.
Build a base
Lay foundations, walls, doorways, floors and stairs, then upgrade them with a hammer from sticks to wood to stone. Lock your doors with a code, and place a tool cupboard so nobody else can build on your ground. Put down a sleeping bag to come back to when you die.

Fight
Make melee weapons, bows and crossbows, and assemble guns from the parts you find. Wear armor against blades, arrows and blasts, and bandage your wounds. When you die, everything you carry drops in one bag for whoever gets there first. Talk to anyone near you with proximity voice chat.

Raid
Guns don't break walls. Wood gives way to axes if you have the time; stone and metal only to explosives. Make gunpowder, craft charges, blow the door and take what's inside. Defenders can defuse a charge before it goes off.

Meteor showers
Meteors fall without warning. Their craters hold the best metal on the planet, and the smoke they leave shows everyone where they landed.

Launch sites
Four launch sites stand locked down and guarded, with supplies inside. Get past the guards, force the loading bay's gate while the alarm sounds, and take the crates. Each time a pod comes home, it brings fresh supplies and fresh guards.

Every world ends
It grows in the sky night after night. After thirty days it arrives, the server wipes and nothing carries over. Then a new world begins on the same server. The server browser shows how far along each world is, so you can join on the first day or the last.

Ashwend is free to play.
