I had trouble finding anything in the second area. Maybe it is too large? The only mine I did find disappeared from sight when I tried to dig it up. The detector still beeped over it though.
Heeey! Thank very much for playing. Yeah, about second level, I agree with you, it is quite big. Even I couldn't find every mine. Out team haven't much time to end this project properly and it is only testing. Btw, sorry for that late responce
