Please help. This was a Windows game I played around 1994 or 1995 and it came on 3 or 4 discs. You explore an uninhabited tropical island which has been polluted by radiation and you have to get rid of the radiation by solving puzzles. It had CG graphics.
Perhaps EcoQuest? https://en.wikipedia.org/wiki/EcoQuest
No it wasn't a DOS game it was for Windows 3.1 and 95.
How sure? Around that time, a lot of games were still DOS, and Windows machines were often rebooted into DOS.
