Dark Earth
 

Action-adventure game. Publisher (MicroProse) is ESA member, but now the game is unprotected. Only used copies at Amazon.

Is it abandonware?

Ouch, the game is at ISO Cellar! My mistake!

No problem, simply moving this to Approved for ISO Cellar. You were only a bit to late, and as it is unprotected only since few days, you couldn't expect it to be at the ISO Cellar. ;)

Very thanks! :D
