RETRO AT HEART.BUILT TO CREATE.
BlastIII brings the hands-on spirit of classic sector editing into a connected toolkit. Draw the space. Give it atmosphere. Make it playable.
Room over roomMake the arsenal your own.
Assemble photographic sci-fi parts, animate their mechanisms and author the shot itself. Sockets, timelines, ejected parts, beams and layered projectiles share one creative workflow.
Assemble from partsGive every moment an impact.
Slow the world while keeping an edge in movement. Refractive shot wakes, physical debris, persistent blood, surface fire and spatial sound give combat a tangible aftermath.
The aftermath staysTake your world further.
Build a linked campaign or a competitive arena. Play with bots, connect through direct IP, and export a standalone game with its own title, presentation, settings and saves.

- Visual projectile size stays separate from collision
- Original artwork remains intact
Tune the built-in weaponsGive the player another option.
Reflected Prism Laser beams, piercing Railgun shots, sticky charges, Micro Rocket Swarms and deployable Sentry turrets bring distinct behaviours to the built-in arsenal. Their pickups and optional enemy drops use the same authoring workflow.
- Dedicated secondary weapon slots and pickups
- Shared damage, collision and world interaction
Deploy a sentrySlow the world. Keep your edge.
Bullet time slows the world to quarter speed while player movement retains an advantage. Shot paths create refractive pressure wakes through the scene; world sound follows the slowed clock.
- Twelve real seconds of rechargeable charge
- Campaign and offline bot matches; disabled online
Refractive shot wakesReveal the refractive wake Build the encounter.
Author enemy groups, triggered waves, group-clear actions and death drops. Ground and flying enemies navigate the actual level, while bosses bring distinct attack patterns and enraged phases.
- Switches, access cards, secrets and linked exits
- Destructible props and occluded chain reactions
Build the encounterA physical aftermath.
Debris, casings and fragments collide and settle. Blood stays attached to surfaces, explosions respect foreground geometry, and residual fire follows the floor, wall or ceiling it touches.
- Pressure refraction and distance-based blast shake
- Placeable ground fire and ceiling short circuits
The aftermath staysEnemy Studio.
Draw arbitrary polygon masks over the original enemy views. Preview dismemberment with the same physics used in play, then keep the profiles with the enemy assets.
- Per-view masks, point editing and independent Undo
- Shared humanoid fallback; mechanical enemies stay flesh-free
Preview the breakupSound belongs in the world.
Enemy voices, weapon impacts, explosions, casing contacts, doors and lifts use positional sound. Personal feedback remains centred as the listener moves and turns.
- Independent effects, music and personal volume
- Optional recordings for individual gameplay events
Control the audio mixHear left, front and right Change a sound. Hear it in Play.
Add, replace or remove effect WAVs while testing. The engine discovers the changes during Play, so iterating on an event does not require rebuilding the game.
- Numbered recording variants
- Original files stay unchanged
Time the mechanismMusic that fits the space.
Select an optional OGG Vorbis or MP3 track per level. Stereo streaming and an independent music level preserve the recording's character through pause and slow-motion combat.
- Music keeps its speed during bullet time
- Portable audio is included in standalone exports
Music per levelFeel the shift in time.
World effects change speed and pitch with bullet time, including sounds already playing. Personal transition and heartbeat recordings keep their original speed.
- Reverse transition feedback on leaving slow motion
- Pause retains queued sounds and music

Quad Damage, Overdrive, Vampire, Blast Core, Arc Surge, Chrono Anchor, Kinetic Shell and Gravity Well bring damage boosts, chaining hits, a lethal-hit recall, stored blasts and pulling force.
- One active powerup, timed respawns and contested drops
- Carrier highlights, countdowns and HUD feedback
Powerup feedback in PlayIterate without losing the map.
F5 moves from editing to testing. Isolate selected rooms in both views, retain independent Studio histories and use automatic editor recovery. Read-only checks include advisory routes to keys, exits and buttons; they do not simulate every jump or timed mechanism.
- Save As keeps map textures portable
- Game sessions stay separate from editor documents
Inspect the levelMenus, saves and a readable HUD.
A scalable player HUD presents vitals, ammunition, time charge and transient weapon selection. Full game sessions support quicksave and six thumbnail-backed manual slots.
- Configurable gameplay controls and HUD scale
- Frame limiting independent of the 120 Hz simulation
Keep your placeExport your own game.
Package linked levels, textures, runtime art, audio and Studio loadouts with your chosen game title. Select a render height from 240p to 1080p or Native, with optional texture and atlas optimization.

A FEW MORE DETAILS
UNDER THE HOOD.
What kind of engine is BlastIII?
An independent C++20 retro FPS engine and sector-based editing toolkit. Its 3D scenes use OpenGL GPU rendering, photographic sci-fi artwork and crisp retro sampling.
The live editorCan I make a standalone game?
Yes. Export game packages a saved starting map, linked levels, portable textures, runtime artwork, audio, weapon settings and assigned Studio designs. Choose the game title, render height and optional image optimization. The exported game starts directly in Play, with its own settings and saves; authoring masters stay unchanged.
Export resolution and assetsWhat about multiplayer?
Direct-IP cooperative campaign and Deathmatch support 2–8 players. The host runs authoritative simulation with client movement prediction, remote interpolation and bounded instant-shot lag compensation. Players need matching maps and assets. Offline Deathmatch supports bots; eight powerups work in arenas. Bullet time and cheats are disabled online.
Host a shared sessionCan the source build without downloads?
The repository includes the pinned project dependencies and build fallbacks for offline builds. A suitable compiler, operating-system development SDK and graphics driver must already be installed. Windows uses the permanent build and installation workflow; Linux and macOS have native build entry points, with runtime validation still pending on those platforms.
The live editorWhere can I get it?
BlastIII is in active development. This page is a showcase of its current tools and visuals; a public release and download are not available here yet. Windows is the current verified development platform; native Linux and macOS workflows still require platform testing.
