About this game
Beast Siege is an online co-op game where ordinary warriors take on colossal Beasts. In a medieval fantasy world without magic, they rely on gunpowder technology for explosive recoil jumps, gunpowder-powered hammer strikes, and more.
Experience the next generation of gaming with fully physics-driven interactive combat and seamless network synchronization.
Every movement of the gigantic Beasts reacts to player actions through real-time physics interactions, allowing them to overcome obstacles naturally and create lifelike motion never seen before in any game.
Climb the Colossal Beast and Smash Its Head!
Climb up the giant beast by stepping on its legs.
Use the explosive recoil from your hammer to launch yourself into the air and land a powerful blow to its head.
True Physics, Real Reactions
Right cheek. Chin. Left cheek.
Each strike sends the beast’s head snapping to the side.
This isn’t an animation. It’s real physics, in real time.
One Devastating Blow — Can You Handle It?
One swing of the beast’s tail is all it takes.
Get hit, and you’re sent flying—no time to react.
Dodge early, or block with everything you've got.
You Can Stop It—If You Work Together!
With enough hands, you can pin the beast down using harpoons.
But it won’t last long. Finish the job before they snap!
The Moment the Beast's Leg Is Trapped
Once the beast is caught in a trap, it can no longer use that leg properly.
But it won’t last long—finish the fight before the trap breaks!
Enjoy all this incredible gameplay in online co-op!
