About this game

You are the Simulor.

A weapon of war, built for purpose.

Launched from the mothership in your escort craft,

you fight with nothing but the mouse.

━━━━━━━━━━━━━━━━━

One Mouse. One Hand.

Aim and movement, unified.

Weapon swaps trigger a split-second slow — room to think.

Boost and dash carve survival through the bullet storm.

━━━━━━━━━━━━━━━━━

Sets Complete the Build

Gather gear of the same line to unlock set effects that reshape how your Simulor fights.

━━━━━━━━━━━━━━━━━

Greed Is Strength

Acquire new gear and enhance it.

The more of the same weapon you stack,

the deadlier it becomes.

━━━━━━━━━━━━━━━━━

Something Waits for You

At the end of every stage, a force far greater than you.

━━━━━━━━━━━━━━━━━
