Siege Outpost: The Survival - 3D FPS Defense Game
Siege Outpost: The Survival is a free 3D first-person defense shooter. Deploy to the field, hold your outpost against relentless hostile waves, switch between four weapons on the fly, and bank credits to survive as long as you can. No download, no sign-up — play instantly in your browser.
How To Play Siege Outpost
Move with WASD or the arrow keys and aim with the mouse. Left-click to fire, and switch weapons with keys 1–4: Rifle, Shotgun, Sniper, and Bomb. Jump with Space to reposition. Clear each hostile wave to earn credits and keep the outpost standing. On tablets, drag to look and use the on-screen buttons.
Four Weapons, Every Range
Each weapon shines at a different distance: the Rifle for steady mid-range fire, the Shotgun for close swarms, the Sniper for picking off distant threats, and the Bomb for clustered enemies. Reading the wave and swapping to the right tool at the right moment is the core of surviving the siege.
Hold The Line
Hostiles attack in escalating waves that grow larger and more aggressive the longer you last. Manage your armor, keep moving between cover, and use credits to push your run further. Every wave held is more score banked and another step toward the ultimate survival record.
