Got 1000GS in 2 days! Very easy, I would agree 6-8 hours to complete!
I found very little difference in Elite Agent and Agent, only 3 main differences;
1- Aliens generally take a bit longer to kill, but since you will have upgraded weapons this time round it will easier at the beginning.
2- Nakkadan Elite Guard is slightly harder as he breaks into 4 instead of 3, so regenerates more health.
3- Last boss takes longer and will attack more often/harder.
Regarding avoiding the mines,
I thought I had done it but somehow I must of touched it so just be sure you have avoided them all or restart, or else you must play the whole chapter again!
Good guide, helped me a lot!
