One link. 12 players. One alien world. Starfall Prime is a free 3D survival game that runs in a browser at starfallprime.com — no download, no signup, no install, on a phone with touch controls or on a desktop. You crash-land alone on an alien world, follow a red emergency beacon to your downed ship, and carry seven scattered ship parts home one at a time to escape.
Enemies are rigged skeletons walking on procedurally animated legs, and every shot resolves limb by limb — the game knows exactly which bone your beam passed through. Hit one and it launches backward through the air, tumbling, the struck limb leading the fall; a leg shot sweeps its legs out from under it. A body part tears off with every hit — an arm, a leg, the skull. They get back up three times, and you can keep shooting them while they are still airborne, juggling a body across the field. The fourth hit scatters them into loose bones.
Laser fire reflects off crystals and off player shields at the true angle of incidence, up to three bounces, so you can bank a shot around cover. Crystals are indestructible mirrors. Shields turn incoming fire away, but every deflection costs the owner a charge.
Drag to walk, run, backpedal and turn. Tap to fire your laser cannon. Switch to build mode to place walls that snap together into a sealed perimeter, swing them into position, and mount turrets that track and shoot on their own. Grenades arc over cover. Nights go pitch black, and your helmet flashlight is the only thing keeping you alive.
Up to 12 players share one world — co-op or free-for-all PvP — joined by an invite link or by browsing public sessions. Everyone sees the same monsters, the same destruction and the same fort. There is a global top-100 leaderboard. Future versions add more alien types and more physics.
