Blam! Machinehead PC Demo (also for the Sega Saturn and Sony Playstation) featuring one level where you must destroy 10 cocoons, navigate the aqueduct turbines, restore power to the train generator, then follow it to the level exit. Collect green Unreality Keys (and one normal red key) to warp reality around you to progress through the level while hovering on a gun-totting self-destructing warhead!
Keyboard controls can be rebound and is recommended to do so within the options.
Ram into the Unreality Terminals at speed to use your Unreality Keys on them.
While this game works better in local DosBox under Auto (browser version cannot seem to handle Core set to Auto, only Simple), it can be streamed in the browser version well enough. I have manually set Cycles to 71000, Prebuffer to 20, and audio Blocksize to 4096 to strike a balance between performance and audio skipping.
