Steam now offers early access to 3030 Deathwar Redux, a reworked version of this Windows game described by its developers as "a unique mixture of old-school Adventure game and Space Combat and Trading Sim." This video shows what that looks like, and here's word on the game and its reduxification:

After a dead body is found by his crew, then his new ship gets impounded by the cops, something is going on... probably related to a missing freighter with a large cargo of gold bars. Now, John Falcon, a freewheeling space pilot, tries to get back on his feet. But where to start?

• Take on some local delivery jobs and get a better ship?
• Downsize to a Jetsuit and go shooting space-junk for quick money?
• Focus on finding the missing gold shipment before the local gangs and salvage teams?
• Go punch that damn mechanic who sold you a stolen ship?
  ...and what is this mysterious 'Taoist' group you keep hearing about?

Maybe just take a break and go travelling inter-stellar, in an Open World of more than 30 star systems.

The Redux version adds: an extended adventure, with extra characters and side quests, space races, lots of graphical enhancements, balancing and gameplay changes, a smoother tutorial and tons of other improvements!
