BIOFRACTURE

Bio-mechanical survival — top-down — infinite pressure

Engine Godot 4 / GDScript
Genre Survivor-like / Roguelite
Status Active Dev
// premise

You are a Diver — an explorer who crash-landed on a giant robotic organic mass drifting through deep space. The impact infected you with an alien mutation virus. One arm is now fully robotic. The other is mutating.

The mass is alive. It's building an immune response. Survive it.

// core systems
01 — COMBAT
Autogun + Melee Hybrid
Your robotic arm fires an auto-targeting gun that locks to the nearest enemy in your mouse direction. Hit feedback is layered — red flash, scale pulse, camera nudge, and bio-mechanical layered sound design.
02 — PRESSURE
Living Difficulty Curve
A pressure system ramps spawn rate, enemy density and speed over time. Kill enemies to reduce pressure. Survive long enough and the mass sends tanks.
03 — TIME PULSE
Freeze & Blast
Your signature ability. A shockwave ring radiates from your position — freezing enemies it passes through, blasting those at the edge. Also used for exploration: reveals hidden chests and mutations buried in the mass.
04 — MUTATIONS
Arm Transformations
Found in rare chests. One mutation slot — choosing a new one replaces the old. Each mutation is a total playstyle shift, not a stat bump. First mutation: a grapple arm that removes all normal movement.
// threat escalation
// pressure level — session 1
dormant alert hostile critical ◄

Pressure climbs constantly. Kill speed directly determines your survival window. At critical levels, enemy spawn intervals drop below 1 second and tanks begin appearing in groups. The mass is learning your patterns.

// mutation log — MUT-01
Grapple Arm
// organic-mechanical hybrid limb — classified: unstable

Your mutant arm transforms into a living grapple hook. Right-click to fire — the tendril anchors into terrain up to 500px away. While attached, all normal movement is disabled. You swing on momentum alone.

The cable is a weapon. Enemies that walk into your tether line are shredded by contact damage. Combine with Time Pulse to freeze enemies, swing into position, release — and let your autogun do the rest.

Max tether: 500px Cable dmg: passive Removes: WASD movement Slot: replaces previous mutation
// autogun calibration — pattern log

PAT-02 Burst Fire 3 rounds per volley in a spread cone. Lower damage per bullet, higher area coverage. level 5
PAT-03 Overcharge One devastating round at 2.8x damage. Slow fire rate. Heavy knockback on impact. level 5
PAT-04 Twin Barrel Two parallel shots simultaneously. Full damage each. Wider coverage without spread loss. level 5
PAT-05 Suppression Rapid low-damage fire. 3x fire rate. Constant pressure, slight random spread. level 5
