Rex and the Galactic Plague

QUICK UPDATE: Stability Fix

Memory issues caused Rex to hang on booting on certain configurations. I've made some fixes to correct this, so as long as you have 1mb it should be working! 

Rex and the Galactic Plague – Final Demo Update

It's been a while but hopefully will be worth the wait!

As Rex and the Galactic Plague enters its final stages of development, I’m releasing one last update to the demo, bringing together all the major changes and improvements made since the previous release.

What’s new in this final demo?

• The two earlier demo versions have been combined: this final version includes the first three full levels of the game
• The weapons system has been completely overhauled, replacing the original two upgradable weapons with nine distinct weapons (a selection of which are available in the demo)
• New defensive items give Rex extra chances to survive the Amorni assault—though they’re rarer now, so use them wisely
• The HUD has been refined to prevent game pauses when loading and unloading boss health bars
• All story and presentation screens have been reworked to better tell Rex’s story and create a more cohesive world
• A high score table now tracks your best score—or rather, your field rank (as Space Corps would have it!)

I’ve worked hard to ensure this all runs on a base Amiga 500+ (in my mind, it isn’t really a game unless I can run it on my own machine!). That’s meant making some tough structural decisions to keep everything within memory limits. As the game grew—now up to 9 levels (five more than originally planned!), 10 weapons, and 5 defensive upgrades—the past few weeks have been spent furiously streamlining and reorganising to keep it all running smoothly.

There’s still plenty left to do. The second half of the game needs more extensive playtesting, and further work is required to ensure the full game runs reliably on an A500+ (mine is from the wonderful Cartoon Classics bundle, if you’re curious). With any luck, this will be the final demo—my focus now shifts to preparing a full release later in 2025. That timing depends on how long it takes to polish remaining issues—and whether multi-disk support in Scorpion lands soon enough (I know it’s on the way!).

So please give this latest demo a spin—if nothing else, to see how far it’s come since that first version back at the start of the year. And if you have any feedback—constructive, critical, or otherwise—I’d love to hear it in the comments.

The next update should be the full release, barring anything going drastically wrong.

Until then, log in to Osiris and check your latest Space Corps directives. There’s a pandemic to neutralise.

Oh and don't be looking at intel beyond your pay grade. Space Corps takes no responsibility for any negative effects.

Rex and the Galactic Plague

A hybrid sci-fi shooter for the Commodore Amiga

A deadly virus is wreaking devastation across the stars, reducing civilisations to dust in its wake. Space Corps is overwhelmed and the Amorni - a remorseless synthetic species at the heart of the outbreak - are exploiting the chaos.

There is only one hope - REX, a remote exocontainment unit repurposed for this final, critical mission. Armed and adapted for survival, Rex has been tasked with recovering a vital and life-saving vaccine from the shattered remains of the Thoros Foundation.

But the Amorni are closing in as the virus spreads, and the closer Rex gets to harder they fight...

• Battle through several different zones, from crumbling facilities to asteroid fields
• Survive ground and space-based missions with nothing but your wits and the finest Space Corps hardware
• Fight your way to two different endings and alternate routes
• Uncover the secret of the Amorni plan to destroy all life

Can Rex complete the mission in time before all life is extinguished?

Controls

This demo gives you a chance the play the first three levels. Escape the Thoros Foundation with the vaccine and survive a desperate dash through space!

All controls and descriptions of weapons and defensive items are available in-game from the main menu,

Background

This vertical shooter for the Commodore Amiga started off life as a SEUCK game back in 1993 but has been brought to life again thanks to the fantastic Scorpion Engine.

It's also my first game, which just goes to show how amazing Scorpion Engine is at giving someone as non-technical as me the chance to create games!
