They still have a website.
Another old DOS game I like is Seawolf.
688 Attack Sub or something like that.
Snooping around using sonar is a blast.
Let me know if you get ef2000 running.
Good luck.
Pull up! Pull up! Pull up!
I’ll have to fill my PC case first (and probably replace the power supply I bought for it 15 years ago).
Nice enough case that I’ve hung onto it that long, but lacked interest in investing in the hardware while lacking a decent game to play.
