This is an unfinished (but fully playable) Unreal 2 level (based on the PC Games tutorial I wrote in 2003) that I released to the community. No scripting or particle effects, but the map is fully playable and provides at least 30 minutes of gameplay. See if you can find all secret areas, there’s three dead hidden scientists! More information can be found in the Solaris Base readme.
