A downloadable game

A fast-paced bidirectional horizontal shooter – and perhaps too fast for some of the armchair scroller fans, but what do I care, I need speed. 

To sweeten the deal, you get infinite continues, nine levels of weapon power-up, built-in trainer modes, portals and respawn points.  So battle your way through a gigantic 32k pixel-wide level to find and destroy the end boss.   

You need to pick up fuel barrels to keep your spaceship afloat.  If you activate both sides of a colour-coded portal, you can reap the benefits of hyperspace and travel instantaneously.  Doors require buttons to be pressed.

Key mapping:

  • M : Music on/off
  • Space : Pause
  • H : Half-speed trainer
  • I : Invulnerability trainer
  • O : Overtime


The game is PAL only and uses VSP for scrolling, so you may encounter some problems on a small subset of original C64 hardware that has the VSP bug.  It has been tested on several C64/C128, TheC64 and emulators.

Great game with great music, thank you. I also included it in my new "Gameplay of New C64 Games from October 2024" video, in addition to the other C64 games released in October.

Very nice and fast, but hard shooter with great scrolling! Our German-language review can be found in our recorded livestream starting at 01:28:07. English subtitles are also available. Subscription to our YouTube and Twitch channel is welcome. 🙂

Is it possible that the [O]vertime cheat does not work? I presume that time is the bar below the lives counter.

I just verified again, that it is working by using a vice screen recording.  Without overtime the fuel tank lasts for 15 seconds and with overtime for 30 seconds.  So it seems to work.

Ah OK, just a slowdown.
