Impromptu Games is an independent game development studio based in Melbourne, Australia.
We make video games,
and tools to help other people make video games.
We're often available for contract work. Enquire here.


Currently, we're developing a first-person stealth game for PC and PS4, using Unreal Engine 4.
You can follow our progress on Joe Wintergreen's dev blog and Twitter.




Shipped Games




Stolen Steel VR (2017) is a room-scale VR arena swordfighting game for HTC Vive and Oculus Rift. Steal a sword and fight increasingly tough AI opponents in pursuit of the highest score. Get extra points for stealth kills, and compete with your friends to determine the superior swordsperson. Made with Unreal Engine 4. InFlux (2013) is a puzzle game that mixes exploration and puzzle platforming in a series of beautiful natural and abstract environments. You are a mysterious metal sphere which falls from the sky, traversing an apparently deserted island dotted with cubic structures of glass and steel.
Made with Unreal Engine 3.


Vroom! (2011) was a racing spin-off of Shotgun Sunrise available for iOS, made with Unreal Engine 3. Shotgun Sunrise (2009) was a multiplayer zombie-Western total conversion mod for Half-Life 2.

Client Projects


We undertake consulting and contract work from time to time, often under NDA.
Here are some of the less confidential jobs.



Primal Carnage Onslaught, by Pub Games, is the VR spin-off of the popular Primal Carnage FPS series. Pub contracted us to help with various polish such as effects, gun-feel and tutorial systems.

The Siege and the Sandfox is an upcoming 2D Stealthvania being built on UE4 by Cardboard Sword, and we're helping out with various Blueprint systems, including taking charge of the game's AI.



Immersive Entertainment contracted us to assist with various aspects of their Grand Canyon VR Experience. Among other things, we handled the technical implementation of motion-controlled rowing, and all of the artificial intelligence systems (butterflies which alight on surfaces, feedable fish, etc).



Tools
We also sell various tools, systems, and example projects on the Unreal Engine Marketplace and Itch.io.


This tool lets you paint and visualise 3D vector fields in real-time, optionally in VR, inspect them from all directions, and save them out to .FGA format for use in whatever software, or your own games. Corkboard is a multiplayer post-it/discussion system created in UE4 Blueprint. A good learning resource for anyone struggling with implementing basic multiplayer.


Impromptu Ladders

A highly flexible procedural ladder blueprint which lets you create detailed ladders of any length and proportions in seconds, simplifying the normally tedious and inefficient task of creating bespoke ladders to fit spaces in your levels. Creating a ladder of the perfect height, width and depth is as easy as clicking and dragging. A huge time saver for any game with ladders in it.


Impromptu Handrails

A highly flexible procedural handrail Blueprint which lets you create detailed, highly customisable handrails of any length and proportions in seconds, simplifying the normally tedious and inefficient task of creating bespoke handrail meshes for your levels or glueing them end-to-end and hoping for the best. Creating a handrail of the perfect length is as easy as clicking and dragging. A huge time saver for any game with handrails in it. 
Impromptu Stairs

A procedural staircase Blueprint which lets you create detailed, highly customisable linear staircases in seconds out of instanced meshes, which is less annoying than pretty much any other way of making staircases. A huge time saver for any game with stairs in it.





Impromptu Fire Propagation

A fire propagation system, similar to that found in the Far Cry series, created entirely in Blueprint. Fire can spread realistically across staticmeshes, landscapes and BSP.












Speculative Projects

These are projects which aren't being as actively developed, and may or may not see eventual release.



Spacething is a first-person sci-fi adventure game where you renovate a spaceship and go on an interstellar road trip with your friend the sentient shipboard AI. Magenta Sunset is a currently-mysterious immersive, atmospheric first-person adventure game with a focus on minute interactivity. Extreme Bicycle '64 is a return to the fondly-remembered multiplayer futuristic sentient-motorbike deathmatch genre.
